Based on the Variation of Information (VI), normalized by the maximum entropy. +//! +//! `NTE(X,Y) = (H(X|Y) + H(Y|X)) / max(H(X), H(Y)) = (2H(X,Y) - H(X) - H(Y)) / max(H(X), H(Y))` +//! +//! ### 4. Mutual Information (MI) +//! Measures the amount of information obtained about one random variable by observing another. +//! +//! `I(X;Y) = H(X) + H(Y) - H(X,Y)` +//! +//! ### 5. Divergences & Distances +//! * **Total Variation Distance (TVD)**: `δ(P,Q) = 0.5 * Σ |P(x) - Q(x)|` +//! * **Normalized Hellinger Distance (NHD)**: `sqrt(1 - Σ sqrt(P(x)Q(x)))` +//! * **Kullback-Leibler Divergence (KL)**: `D_KL(P||Q) = Σ P(x) log(P(x)/Q(x))` +//! * **Jensen-Shannon Divergence (JSD)**: Symmetrized and smoothed KL divergence. +//! +//! ### 6. Intrinsic Dependence (ID) +//! Measures the redundancy within a sequence, comparing marginal entropy to entropy rate. +//! +//! `ID(X) = (H_marginal(X) - H_rate(X)) / H_marginal(X)` +//! +//! ### 7. Resistance to Transformation +//! Quantifies how much information is preserved after a transformation `T` is applied. +//! +//! `R(X, T) = I(X; T(X)) / H(X)` +//! +//! ## Usage +//! +//! ```rust,no_run +//! use infotheory::api::{mutual_information_marg_bytes, try_ncd_paths, NcdVariant}; +//! +//! let x = b"some data sequence"; +//! let y = b"another data sequence"; +//! +//! // Compression-based distance +//! let ncd = try_ncd_paths("file1.txt", "file2.txt", "5", NcdVariant::Vitanyi) +//! .expect("ncd");

This crate provides a comprehensive suite of information-theoretic primitives for -//! quantifying complexity, dependence, and similarity between data sequences. -//! -//! It implements two primary classes of estimators: -//! 1. **Compression-based (Kolmogorov Complexity)**: Using the ZPAQ compression algorithm to estimate -//! Normalized Compression Distance (NCD). -//! 2. **Entropy-based (Shannon Information)**: Using both exact marginal histograms (for i.i.d. data) -//! and the ROSA (Rapid Online Suffix Automaton) predictive language model (for sequential data) -//! to estimate Entropy, Mutual Information, and related distances. -//! -//! ## Mathematical Primitives -//! -//! The library implements the following core measures. For sequential data, "Rate" variants -//! use the ROSA model to estimate `Ĥ(X)` (entropy rate), while "Marginal" variants -//! treat data as a bag-of-bytes (i.i.d.) and compute `H(X)` from histograms. -//! -//! ### 1. Normalized Compression Distance (NCD) -//! Approximates the Normalized Information Distance (NID) using a compressor `C`. -//! -//! `NCD(x,y) = (C(xy) - min(C(x), C(y))) / max(C(x), C(y))` -//! -//! ### 2. Normalized Entropy Distance (NED) -//! An entropic analogue to NCD, defined using Shannon entropy `H`. -//! -//! `NED(X,Y) = (H(X,Y) - min(H(X), H(Y))) / max(H(X), H(Y))` -//! -//! ### 3. Normalized Transform Effort (NTE) -//! Based on the Variation of Information (VI), normalized by the maximum entropy. -//! -//! `NTE(X,Y) = (H(X|Y) + H(Y|X)) / max(H(X), H(Y)) = (2H(X,Y) - H(X) - H(Y)) / max(H(X), H(Y))` -//! -//! ### 4. Mutual Information (MI) -//! Measures the amount of information obtained about one random variable by observing another. -//! -//! `I(X;Y) = H(X) + H(Y) - H(X,Y)` -//! -//! ### 5. Divergences & Distances -//! * **Total Variation Distance (TVD)**: `δ(P,Q) = 0.5 * Σ |P(x) - Q(x)|` -//! * **Normalized Hellinger Distance (NHD)**: `sqrt(1 - Σ sqrt(P(x)Q(x)))` -//! * **Kullback-Leibler Divergence (KL)**: `D_KL(P||Q) = Σ P(x) log(P(x)/Q(x))` -//! * **Jensen-Shannon Divergence (JSD)**: Symmetrized and smoothed KL divergence. -//! -//! ### 6. Intrinsic Dependence (ID) -//! Measures the redundancy within a sequence, comparing marginal entropy to entropy rate. -//! -//! `ID(X) = (H_marginal(X) - H_rate(X)) / H_marginal(X)` -//! -//! ### 7. Resistance to Transformation -//! Quantifies how much information is preserved after a transformation `T` is applied. -//! -//! `R(X, T) = I(X; T(X)) / H(X)` -//! -//! ## Usage -//! -//! ```rust,no_run -//! use infotheory::{ncd_vitanyi, mutual_information_bytes, NcdVariant}; -//! -//! let x = b"some data sequence"; -//! let y = b"another data sequence"; -//! -//! // Compression-based distance -//! let ncd = ncd_vitanyi("file1.txt", "file2.txt", "5"); -//! -//! // Entropy-based mutual information (Marginal / i.i.d.) -//! let mi_marg = mutual_information_bytes(x, y, 0); -//! -//! // Entropy-based mutual information (Rate / Sequential, max_order=8) -//! let mi_rate = mutual_information_bytes(x, y, 8); -//! ``` - -/// AIXI planning components, environments, and model abstractions. -pub mod aixi; -/// Core information-theoretic axioms and validation helpers. -pub mod axioms; -/// Entropy/compression backend implementations and backend discovery. -pub mod backends; -/// Entropy coder implementations (AC and rANS). -pub mod coders; -/// Rate-coded compression helpers built on generic rate backends. -pub mod compression; -/// Synthetic data generators for information-theory experiments. -pub mod datagen; -/// Diagnostic tooling for exact AC/log-loss mixture tracing. -pub mod diagnostics; -/// Online Bayesian/switching/MDL mixture predictors. -pub mod mixture; -pub(crate) mod neural_mix; -/// Information-theoretic code search pipeline (3-stage: prefilter, filter, KMI rerank). -pub mod search; -pub(crate) mod simd_math; -/// CTW and FAC-CTW backend types. -pub use backends::ctw; -#[cfg(feature = "backend-mamba")] -/// Mamba backend types and compressor. -pub use backends::mambazip; -/// Match-based repeat predictor. -pub use backends::match_model; -/// Particle-latent filter ensemble rate backend. -pub use backends::particle; -/// PPMD-style byte model. -pub use backends::ppmd; -/// ROSA+ backend types. -pub use backends::rosaplus; -#[cfg(feature = "backend-rwkv")] -/// RWKV backend types and compressor. -pub use backends::rwkvzip; -/// Exact online Sequitur backend types. -pub use backends::sequitur; -/// Sparse/gapped match predictor. -pub use backends::sparse_match; -/// ZPAQ rate-model adapter. -pub use backends::zpaq_rate; - -use rayon::prelude::*; - -use crate::coders::CoderType; -use std::cell::RefCell; -#[cfg(any(feature = "backend-rwkv", feature = "backend-mamba"))] -use std::collections::HashMap; -use std::sync::Arc; -use std::sync::OnceLock; - -/// How generated symbols should update the model state. -#[derive(Clone, Copy, Debug, PartialEq, Eq)] -pub enum GenerationUpdateMode { - /// Keep adapting/fitting on generated bytes. - Adaptive, - /// Freeze fitted parameters/statistics and only advance conditioning state. - Frozen, -} - -/// How to pick the next byte from the model distribution. -#[derive(Clone, Copy, Debug, PartialEq, Eq)] -pub enum GenerationStrategy { - /// Deterministic argmax over the next-byte distribution. - Greedy, - /// Seeded sampling from the next-byte distribution. - Sample, -} - -/// Generation options shared by the library API and CLI. -#[derive(Clone, Copy, Debug)] -pub struct GenerationConfig { - /// Byte-selection strategy. - pub strategy: GenerationStrategy, - /// Whether generated bytes should keep adapting the model. - pub update_mode: GenerationUpdateMode, - /// RNG seed used by [`GenerationStrategy::Sample`]. - pub seed: u64, - /// Softmax temperature for sampling. `<= 0` behaves like greedy. - pub temperature: f64, - /// Optional top-k truncation. `0` disables it. - pub top_k: usize, - /// Optional nucleus truncation.

Predictive Tuning:\\A Formal Algorithmic Specification} +\author{Noah Cashin} +\date{\today} + +\begin{document} +\maketitle + +\section{Purpose and Scope}\label{sec:purpose-scope} + +This document specifies a constrained predictive/compression tuning capability for a fixed dataset. +The specification is intended to be: +\begin{itemize} + \item mathematically precise, + \item directly implementable in \texttt{infotheory}, + \item optimizer-agnostic at the interface layer, + \item runtime-selectable between annealed hill climbing, + MC-AIXI(FAC-CTW), discounted AIQI, and a distinct exact + warm-start controller, and + \item mathematically explicit about objective alignment in each controller path. +\end{itemize} + +This capability is \emph{not} an unconstrained architecture search engine nor a replacement for normal compression execution; it is a bounded optimization wrapper over the same compression semantics. + +\section{Formal Problem Statement}\label{sec:formal-problem} + +\subsection{Objects} + +Let: +\begin{itemize} + \item $x \in \{0,\dots,255\}^{n}$ denote the dataset bytes loaded from \texttt{input\_path}, + \item $\mathcal{Z}$ denote the full configuration space, + \item $B$ denote the user-provided bounds specification, + \item $H$ denote the fixed deployability profile (hardware/evaluator methodology and resource accounting), + \item $z_0 \in \mathcal{Z}$ denote the validated baseline configuration, + \item $T_{\mathrm{eval}} > 0$ denote the hard per-candidate wall-clock limit, + \item $T_{\mathrm{total}} > 0$ denotes the hard total tuning wall-clock budget, + \item $\theta_{\min}>0$ denote the required minimum throughput (bytes/s), + \item $\mu_{\max}>0$ denote the required memory cap (bytes). +\end{itemize} + +Define the bounded-valid candidate set: +\[ +\mathcal{F}(B,H):=\{z \in \mathcal{Z}:\ \mathrm{Valid}_{B,H}(z)=1\}. +\] + +For each candidate $z$, evaluation returns +\[ +M(z) = (\mathrm{status}(z), c(z), \ell(z), \tau(z), \mu(z), \operatorname{diag}(z)), +\] +where +\begin{itemize} + \item $\mathrm{status}(z) \in \{\mathrm{success},\mathrm{timeout},\mathrm{invalid},\mathrm{error}\}$, + \item $c(z) \in \mathbb{N}$ is compressed size in bytes (defined on success), + \item $\ell(z) \in \mathbb{R}_{\ge 0}$ is cumulative negative log-loss (diagnostic), + \item $\tau(z) \in \mathbb{R}_{\ge 0}$ is elapsed wall-clock time, + \item $\mu(z) \in \mathbb{R}_{\ge 0}$ is measured peak memory usage, + \item $\operatorname{diag}(z)$ is optional diagnostics (including invalid-reason tags). +\end{itemize} + +\begin{remark}[Peak-memory measurement semantics] +Each candidate evaluation is executed in its own isolated evaluator instance. + +Preferred definition: $\mu(z)$ is the peak memory usage attributed to that +instance by the operating-system or container memory controller (for example, +cgroup peak memory usage) over the lifetime of the evaluation. + +Fallback definition when such accounting is unavailable: the evaluator must run +as a single process, and $\mu(z)$ is the operating-system reported peak RSS of +that process. + +Naive summation of RSS across a multi-process tree is not normative, because it +can double-count shared pages. +\end{remark} + +Timeout semantics are hard: +\[ +\tau(z) \ge T_{\mathrm{eval}} \implies \mathrm{status}(z)=\mathrm{timeout}. +\] + +For successful candidates, define throughput +\[ +\theta(z):= +\begin{cases} +\dfrac{n}{\tau(z)}, & \mathrm{status}(z)=\mathrm{success},\ \tau(z)>0,\\[4pt] ++\infty, & \mathrm{status}(z)=\mathrm{success},\ \tau(z)=0. +\end{cases} +\] +Define the equivalent throughput runtime cap +\[ +\tau_{\theta}:=\frac{n}{\theta_{\min}}. +\] +Then, for successful candidates, +\[ +\theta(z)\ge\theta_{\min} +\iff +\tau(z)\le\tau_{\theta}. +\] + +\subsection{Primary Objective} + +Define model-code length by canonical bytes +\[ +L_B(z):=\big|\operatorname{ser}(\operatorname{canon}(z))\big|. +\] + +For successful candidates, define dataset code length +\[ +C_x(z):=c(z). +\] + +Define the deployable set +\[ +\mathcal{F}^{\mathrm{dep}}(B,H):= +\left\{z\in\mathcal{F}(B,H):\ \mathrm{status}(z)=\mathrm{success}\ \land\ \theta(z)\ge\theta_{\min}\ \land\ \mu(z)\le\mu_{\max}\right\}. +\] + +The normative objective is the totalized deployable two-part MDL criterion +\[ +\mathcal{J}_H(z;x)= +\begin{cases} +L_B(z)+C_x(z), & z\in\mathcal{F}^{\mathrm{dep}}(B,H),\\[3pt] ++\infty, & \text{otherwise.} +\end{cases} +\] + +The primary optimization problem is +\[ +\min_{z\in\mathcal{F}(B,H)}\mathcal{J}_H(z;x). +\] + +\begin{remark}[Operational length units and reporting] +Operational length quantities in this specification are stored and reported in +bytes: $c(z)$, $L_B(z)$, $C_x(z)$, and $\mathcal{J}_H(z;x)$. +Bit-normalized quantities are introduced only in +Section~\ref{sec:restricted-mixture} for semantic/theoretical statements via +the conversion $\text{bits}=8\times\text{bytes}$. +\end{remark} + +\subsection{Deterministic Incumbent Key and Output Semantics} + +For each evaluated candidate $z$, define the deterministic key +\[ +K(z):=\big(\mathcal{J}_H(z;x),\operatorname{ser}(\operatorname{canon}(z))\big), +\] +ordered lexicographically, where $\operatorname{canon}:\mathcal{Z}\to\mathcal{Z}$ +and $\operatorname{ser}:\mathcal{Z}\to\{0,\dots,255\}^*$ are defined in +Section~\ref{sec:canon-cache}. + +For byte strings, use standard lexicographic byte order with strict-prefix +rule: $u\prec_{\mathrm{bytes}} v$ if either (i) at the first differing byte, +$u$ has the smaller byte, or (ii) $u$ is a strict prefix of $v$. + +Let +\[ +\mathcal{S}_t:=\left\{z:\ z\text{ has been evaluated by step }t\ \text{and }z\in\mathcal{F}^{\mathrm{dep}}(B,H)\right\}. +\] +The incumbent is +\[ +b_t:=\arg\min_{z\in\mathcal{S}_t}K(z). +\] +Write $\prec_K$ for lexicographic order on key tuples, i.e. +$K(z_1)\prec_K K(z_2)$ iff the tuple of $z_1$ is lexicographically smaller than that of $z_2$. + +\begin{proposition}[Uniqueness of incumbent under finite deployable evaluated set] +If $\mathcal{S}_t$ is finite and nonempty, then $b_t$ exists and is unique. +\end{proposition} + +\begin{proof} +By construction, $\prec_{\mathrm{bytes}}$ is a

Ensure explicit control over MCTS algorithm choice: WU-UCT, rho-UCT, and a BU-UCT core implementation. There were a few minor inconsistencies in the core rho-UCT algorithm, which have been resolved. Notably, sample size previously promoted MCTS into parallel form automatically, regardless of thread count. Likewise, worse, the parallel form was itself a rather naive and inefficient MCTS form. This went by unnoticed because it is only marginally inefficient with one thread, and was still correct MCTS in a sense when threads=1, just slower. However, parallel MCTS would have been tremendously inefficient before. This is all fixed now. The rho_uct path is now explicit and won't be conflated with parallel MCTS ever again and the API is in better form. This is done with the new `MctsStrategy`, which provides a rho_uct / parallel_uct planner split so far, and optional BU-UCT config parameters, that when set promote the algorithm to a BU-UCT-like system, though without some of the supplementary additions. --- crates/infotheory/Cargo.toml | 4 + crates/infotheory/benches/mcts_planners.rs | 290 +++ crates/infotheory/src/aixi/agent.rs | 146 +- crates/infotheory/src/aixi/common.rs | 85 + crates/infotheory/src/aixi/mcts.rs | 1084 +------- .../infotheory/src/aixi/mcts/parallel_uct.rs | 2206 +++++++++++++++++ crates/infotheory/src/aixi/mcts/rho_uct.rs | 637 +++++ crates/infotheory/src/main.rs | 6 + crates/infotheory/src/spec/document/binary.rs | 36 + crates/infotheory/src/spec/document/parser.rs | 46 + .../infotheory/src/spec/document/pipeline.rs | 31 +- .../src/spec/document/serializer.rs | 18 + crates/infotheory/src/spec/document/tests.rs | 242 +- crates/infotheory/src/spec/document/types.rs | 6 +- crates/infotheory_py/src/lib.rs | 237 +- projman.sh | 28 + python/infotheory_rs/__init__.py | 4 +- python/tests/test_aixi.py | 23 + python/tests/test_api_surface.py | 1 + python/tests/test_predictor_mcts.py | 80 +- python/tests/test_trait_adapters.py | 67 +- scripts/bench_mcts_regression.py | 346 +++ 22 files changed, 4578 insertions(+), 1045 deletions(-) create mode 100644 crates/infotheory/benches/mcts_planners.rs create mode 100644 crates/infotheory/src/aixi/mcts/parallel_uct.rs create mode 100644 crates/infotheory/src/aixi/mcts/rho_uct.rs create mode 100644 scripts/bench_mcts_regression.py diff --git a/crates/infotheory/Cargo.toml b/crates/infotheory/Cargo.toml index 8b653a0a..54b52464 100644 --- a/crates/infotheory/Cargo.toml +++ b/crates/infotheory/Cargo.toml @@ -127,6 +127,10 @@ required-features = ["backend-rwkv", "backend-mamba"] name = "compiled_plan_overhead" harness = false +[[bench]] +name = "mcts_planners" +harness = false + [dev-dependencies] serde = { version = "1.0", features = ["derive"] } sha2 = "0.10" diff --git a/crates/infotheory/benches/mcts_planners.rs b/crates/infotheory/benches/mcts_planners.rs new file mode 100644 index 00000000..2948beed --- /dev/null +++ b/crates/infotheory/benches/mcts_planners.rs @@ -0,0 +1,290 @@ +use criterion::{BenchmarkId, Criterion, Throughput, black_box, criterion_group, criterion_main};

From: Noah Cashin Date: Tue, 28 Apr 2026 17:26:28 -0400 Subject: [PATCH 043/172] More cleanly split algorithmic components from empirical shannon ones where they share a measure formula; Fix legacy `max_order` parameter. I also bumped the infotheory python package, and the rust binding crate for it to version 1.2.0 to match the branches version. I fixed an issue where tests were failing from commit d260dc81 (tests::run_aixi_mode_accepts_canonical_planner_run_documents), which was caused by a mistake. InfotheoryCtx no longer has a `max_order` parameter. Instead, we have seperate empirical and predictive methods, and those are controlled in the CLI by whether or not a RateBackend is specified. Removed Intrinsic Dependence with pure shannon entropy backend, because that is always 0 regardless. Overall, the changes are necessarily sweeping because we were uselessly dragging the max order parameter around despite it being only relevant a specific backend (ROSA), and for triggering "empirical vs algorithmic" measure backends (0=marginal was how it was).

At this point, the specification seems largely implemented, though not necessarily yet with the best quality. The Tuner is feature gated wholly. It is experimental until some useful empirical properties are potentially found. The primary use case is to search the space of configuration for a compressor under specified time and memory limits, and return only a strict improvement or fail to find anything. It can also be used likewise on infotheory AIXI environments, and search the configuration-space for a model that would better predict the outcomes of actions in MC-AIXI in said environment. We introduce a new (approximate) AIXI Agent model, in warmstart.rs. It's not AIQI, but it's based on the idea, and model-less after it warm-starts with MC-AIXI. Because I think that model may work better for the tuner, but experiments are yet to be run. --- .github/workflows/rust.yml | 18 + Cargo.lock | 1 + README.md | 5 + crates/infotheory/Cargo.toml | 2 + crates/infotheory/src/aixi/aiqi.rs | 4 +- crates/infotheory/src/aixi/gameengine.rs | 6 + crates/infotheory/src/aixi/mod.rs | 2 + crates/infotheory/src/aixi/warmstart.rs | 1542 +++ crates/infotheory/src/lib.rs | 3 + crates/infotheory/src/main.rs | 151 +- crates/infotheory/src/spec.rs | 25 +- crates/infotheory/src/spec/document/binary.rs | 87 +- crates/infotheory/src/spec/document/mod.rs | 65 +- crates/infotheory/src/spec/document/parser.rs | 520 +- .../infotheory/src/spec/document/pipeline.rs | 164 +- .../src/spec/document/serializer.rs | 33 +- crates/infotheory/src/spec/document/tests.rs | 71 +- crates/infotheory/src/spec/document/types.rs | 67 +- crates/infotheory/src/tuner.rs | 9321 +++++++++++++++++ crates/infotheory/tests/cli_commands.rs | 7 +- crates/infotheory/tests/tuner_integration.rs | 2795 +++++ crates/infotheory_py/Cargo.toml | 1 + docs/infotheory-tuner-v1.tex | 56 + docs/tuner-v1-traceability.md | 225 + scripts/check_tuner_traceability.py | 160 + 25 files changed, 15164 insertions(+), 167 deletions(-) create mode 100644 crates/infotheory/src/aixi/warmstart.rs create mode 100644 crates/infotheory/src/tuner.rs create mode 100644 crates/infotheory/tests/tuner_integration.rs create mode 100644 docs/tuner-v1-traceability.md create mode 100644 scripts/check_tuner_traceability.py diff --git a/.github/workflows/rust.yml b/.github/workflows/rust.yml index e2313f39..6b12a6a4 100644 --- a/.github/workflows/rust.yml +++ b/.github/workflows/rust.yml @@ -43,6 +43,9 @@ jobs: -

Reports + expose the requested mode, effective measurement, and whether cgroup peak + memory was available.

df2fbe1704b2af878bb3c44758fa23fb77faf86d Mon Sep 17 00:00:00 2001 From: Noah Cashin Date: Sun, 3 May 2026 20:48:04 -0400 Subject: [PATCH 057/172] Complete implementation and submodule refactor for Tuner(v1?) Refactored monolithic `tuner.rs` into modular submodules under `src/tuner/`. Implemented `spawn_exec_worker` isolation for evaluator safety and theorem-facing RSS tracking.

reversibility failure on this dimension was traced to mutation-kind instability at the + `-1 <-> 0` boundary (JSON numeric typing flipped from signed to unsigned by value). +- The kernel now preserves signed integer mutation semantics whenever the configured range has a + negative lower bound, so `max_order` tuning remains enabled without violating reversible-kernel checks. + +Defaults: + +-

PPMD update lookup tightening Replaced contains_key + insert + get_mut with AHashMap::entry. This removes redundant hash-map lookups without changing semantics. PPMD dense interpolation in-place Replaced the old per-context fresh [f64; 256] return with in-place transformation of the existing lower array. This removes a 256-entry temporary/copy per active context. Added a bit-identity regression against the old out-of-place reference. PPMD checkpoint regression Added ppmd_checkpoint_restores_mixed_learned_and_frozen_updates. This specifically guards clone/checkpoint/frozen-history behavior now that suffix keys are part of model state. --- crates/infotheory/src/backends/ppmd.rs | 157 ++- crates/infotheory/src/mixture.rs | 11 + ...erformance-optimization-roadmap-2026-05.md | 1160 +++++++++++++++++ 3 files changed, 1304 insertions(+), 24 deletions(-) create mode 100644 docs/performance-optimization-roadmap-2026-05.md diff --git a/crates/infotheory/src/backends/ppmd.rs b/crates/infotheory/src/backends/ppmd.rs index 2388089d..41636656 100644 --- a/crates/infotheory/src/backends/ppmd.rs +++ b/crates/infotheory/src/backends/ppmd.rs @@ -1,7 +1,9 @@ use ahash::AHashMap;

It is deliberately not a permanent design spec. Its purpose is to keep optimization work scientifically grounded, Hutter-relevant, and resistant to seductive but low-yield micro-tuning. + +The second-pass audit materially changes the prioritization: + +1. **CTW's shared log cache is a Hutter-scale asymptotic memory problem**. The thread-local cache stores `log_int` and `log_half` up to the maximum visit count. At enwik9 scale, two `f64` arrays of length `n` are already about 16 GB before CTW arena state. This must become bounded or optional before CTW/FAC-CTW is a credible Hutter component at full scale. +2. **PPMD's largest exact implementation opportunity is not only suffix hashing**. Rolling suffix keys are valid, but `PpmdModel::ensure_pdf_inner` also rebuilds dense 256-entry arrays across all active orders whenever a caller often needs only one symbol probability or a binary interval mass. The stronger direction is a probability-query interface that avoids dense PDF/CDF materialization when the coder/loss does not require it. +3. **RWKV7's next memory/time work should target TBPTT replay workspace churn before exotic kernels**. Fixed-shape GEMV specialization is plausible, but the current online TBPTT path still allocates replay-local vectors, per-step PDF vectors, traces, checkpoints, full gradient state, and recurrent gradient state per segment flush. Reusing this workspace and freeing it after the final full-train window is a more direct `A(n)/Q(n)/S(n)` target. +4. **Expert marginal utility must be measured explicitly**. Hutter-relevant optimization is not “make every expert faster”; it is “maximize compressed bits saved per byte of memory, second of CPU, and byte of program/model description.” A costly expert that contributes little marginal code-length improvement should be pruned, scheduled sparsely, or made optional before being hand-optimized. +5. **AC inlining and binary decode are now guardrail knobs, not the main research frontier**. They should remain in the benchmark matrix, but further AC work is lower priority unless a new profile contradicts the current evidence. + +## Hutter-aware objective + +For exact implementation optimizations, the predictive distribution and entropy coder semantics should be preserved. For model-changing experiments, the relevant objective is a resource-bounded MDL score, not raw archive size alone. + +Useful decomposition: + +```text +W(n): semantic and implementation arithmetic per byte +Q(n): copied bytes / memory traffic per byte +A(n): allocation events / allocator pressure per byte +S(n): live state size / peak RSS / cache footprint +B: release binary/program/model size after stripping/UPX when relevant +L(n): compressed codelength/archive bytes for the target corpus +``` + +For a Hutter-like candidate, think in terms of: + +```text +J(candidate) = + archive_bytes + + program_and_model_description_bytes + + hard penalties for time, RAM, disk, and decompression failures + + local soft penalties used only for search/ranking +``` + +The implementation tracks in this document should reduce one or more of `W/Q/A/S/B` while preserving `L(n)` exactly or nearly exactly. The model-science tracks may intentionally change `L(n)`, but then they must improve the measured resource frontier rather than merely be “interesting.” + +## Hutter feasibility gates + +The Hutter Prize resource envelope changes which optimizations are rational. For enwik9-scale work, the hard constraints imply: + +```text +input bytes: 1_000_000_000 +time limit: 50 hours +minimum throughput: ~5_556 bytes/s, before decompression/verification overhead +RAM limit: 10 GB +disk limit: 100 GB +target archive: < 110 MB to beat the current record class +``` + +The current 10 MB neural-mixture timing is not obviously time-infeasible under linear extrapolation, but its memory curve is the dangerous term. A 2.6 GiB RSS at 10 MB is already too close to the RAM limit if any major component grows linearly or superlinearly. Therefore the immediate Hutter-relevant question is: + +```text +Can the best compression-effective mixture be made sublinear/bounded enough in memory +while preserving most of its codelength advantage? +``` + +Every proposed optimization should be classified into one of four buckets: + +1. **Feasibility fix**: changes an impossible asymptotic or large constant that blocks enwik9-scale execution. +2. **Frontier improvement**: improves archive/time/RSS Pareto position on verified prefixes. +3. **Search enabler**: makes future model/tuner exploration cheaper without degrading compression. +4. **Cosmetic/local micro-win**: does not change feasibility or the Pareto frontier; deprioritize. + +The first two buckets are the only default priorities for Hutter progress. Search enablers are valuable when they unlock many evaluations. Cosmetic/local wins should be kept only if they are simple, exact, and non-invasive. + +## Evidence baseline + +The current `configs/bench/two.json` neural mixture is: + +```text +ctw(depth=32) +ppmd(order=12, memory_mb=256) +rosaplus(max_order=-1) +match +rwkv7(hidden=64,layers=1,intermediate=64,ranks=16,early full training, long inference tail) +``` + +Representative measured/profile facts: + +- **Neural mixture compression is strong but slow**: for 262144 bytes, neural mixture archive size is around `67454` bytes, versus CTW around `80004` and RWKV around `137010`. +- **Neural mixture runtime is expert-bound**: the neural combiner itself is around 1% self-time in the cited profile; CTW, RWKV, PPMD, and ROSA dominate. +- **Large-prefix memory is expert-state dominated**: 10 MB neural mixture RSS in the current checked-in data is around 2.6 GiB. +- **RWKV standalone RSS is low for the tiny config**, but its arithmetic and training replay are significant. +- **CTW standalone memory and time grow materially**, and its hidden shared-log-cache term is asymptotically dangerous at enwik9 scale. + +Representative 262144-byte neural-mixture compression self-time: + +```text +CtEngine::predict_one ~16.05% +rwkv7::Model::forward_with_sink ~15.74% +rwkv7::Model::accumulate_token_step_gradients ~10.29% +exp ~9.61% +CtEngine::update_prepared ~6.35% +PpmdModel::ensure_pdf_inner ~5.22% +RosaPlus::fill_probs_for_last_bytes ~4.10% +PpmdModel::update ~3.17% +RosaPlus::train_byte ~2.80% +rwkvzip::Compressor::logits_to_pdf ~1.96% +RatePdfPredictor::prepare_cached_cdf_fast_bitwise ~1.77% +NeuralMixCore::compute_context_mixtures ~1.03% +MatchModel::ensure_pdf_inner ~1.02% +``` + +Important current-code facts verified in the second pass: + +- `PpmdModel::context_key(ord)` hashes the suffix from scratch, and `PpmdModel::ensure_pdf_inner` rebuilds dense 256-entry distributions order by order. +- `MixturePredictor::ac_step_bitwise` already uses CTW's bitwise prepared path, and for several non-CTW experts calls `prepare_cached_cdf_fast_bitwise`, which still materializes full CDFs. +- `CtwPredictor::bit_prob_one_msb` already calls `FacContextTree::predict_one`, and `CtwPredictor::update_bit_msb` already calls `update_predicted`. A naive “reuse prediction path for update” idea is redundant. +- `CtEngine::with_logs` uses a thread-local `SharedLogCache` with two `Vec` caches growing to `root_visits + 1`. +- `Model::online_train_segment_tbptt` allocates replay-local gradient/checkpoint/trace/PDF structures inside each segment training call. +- `OnlineRuntime` keeps `full_tbptt` and `full_adam` state after they become unnecessary unless explicit lifecycle logic is added. + +## Acceptance rules + +### Exact implementation optimizations + +Use these for changes that claim not to change the model: + +- **Archive bytes**: exact archive parity is preferred; any byte difference must be treated as a floating-order/model-change event until proven harmless. +- **Roundtrip**: decompressed bytes must equal original bytes. +- **Entropy/loss**: `h` output should be bit-identical or within an explicitly justified floating tolerance only if the operation order changed. +- **Speed**: require a stable whole-subject win, not only a microbenchmark win. For hot expert changes, target at least 1-2% whole-subject improvement or a clear allocation/RSS win. +- **Memory**: for Hutter-scale asymptotic fixes, an optional mode can be accepted even with speed cost if it changes the feasibility class. +- **Binary size**: any specialization that increases text size must report stripped and optionally UPX-compressed binary deltas. + +### Model-changing or compute-allocation experiments + +Use these for expert pruning, approximate scheduling, changed floating semantics, or altered probability models: + +- **Primary**: archive bytes and decompression correctness. +- **Secondary**: time, RSS, temp disk, binary/model bytes. +- **Decision metric**: accept only if the Pareto frontier improves.

Use a finite, auditable search over configurations under the resource-bounded objective `J`. + +Candidate dimensions: + +```text +expert subset: CTW, PPMD, ROSA, Match, RWKV7 +CTW: depth, hot-prefix depth, log-cache threshold/mode +PPMD: order, memory cap, query mode, compact-count mode +ROSA: max_order and bounded-state options if implemented +RWKV7: hidden, layers, ranks, train policy, optimizer, BPTT window +mixture: Bayes/Fading/Neural, learning rates, context features +coder: AC/rANS only if archive/time tradeoff is relevant +``` + +Do not make this an unbounded heuristic sweep. Use a finite grammar and report: + +```text +candidate description bytes +archive bytes +time +RSS +binary/model bytes +verification result +objective J +``` + +The point is MDL discipline: a larger or more complex model must pay for itself in codelength under the actual resource envelope. This search should happen only after CTW/PPMD memory feasibility is no longer confounding the results. + +## Priority table + +| Priority | Track | Main term | Why it is high-signal | +|---|---|---:|---| +| P0 | CTW bounded/exact log lookup | `S(n)` | Current shared cache is `Theta(n)` `f64` memory and can exceed Hutter RAM by itself at enwik9 scale. | +| P0 | PPMD probability-query interface | `W(n), Q(n)` | Avoids dense 256-way interpolation/CDF construction when only `P(symbol)` or binary interval masses are needed. | +| P1 | PPMD rolling suffix keys + update lookup tightening | `W(n)` | Exact `Theta(k^2) -> Theta(k)` key maintenance at order `k`, localized and low semantic risk. | +| P1 | RWKV7 TBPTT replay workspace reuse | `A(n), Q(n), S(n)` | Current full-training replay allocates per segment; profile shows training gradients are expensive. | +| P1 | Expert marginal-utility audit | `L/W/S` | Prevents optimizing costly experts that do not pay their codelength/resource rent. | +| P1 | CTW representation phase diagram | `W(n), S(n)` | Hot-prefix depth and segment representation are a core speed/memory frontier. | +| P2 | PPMD compact continuation storage | `S(n), A(n)` | Likely strong after query/key fixes, but more invasive than rolling keys. | +| P2 | RWKV7 fixed-shape GEMV specialization | `W(n), B` | Plausible for `64/16/256` shapes, but binary-size and floating-order risks must be measured. | +| P2 | ROSA+ probability/memory audit | `W(n), S(n)` | Relevant but more invasive; should follow direct measurement of ROSA's marginal utility. | +| P3 | AC inlining/helper tuning | `W(n)` | Already improved; remaining deltas are likely backend-specific knobs. | + +## P0 track: CTW bounded exact log lookup + +### Files + +```text +crates/infotheory/src/backends/ctw.rs +``` + +### Current implementation + +`SharedLogCache` stores: + +```rust +log_int: Vec +log_half: Vec +``` + +and `with_shared_log_cache(upto, ...)` ensures both arrays contain every entry through `upto`. CTW update/revert paths call this with visit counts derived from `root_visits`. + +At `n = 1_000_000_000`, two `f64` arrays are about: + +```text +2 * 8 * n = 16 GB +``` + +That is already beyond the Hutter RAM limit before nodes, segments, experts, neural state, entropy coder state, and OS overhead. Therefore this is not a micro-optimization. It is a feasibility issue. + +### Hypothesis + +Replace unbounded direct slices with a bounded exact lookup abstraction: + +```text +LogLookup { + cached_int: &[f64], + cached_half: &[f64], + cache_limit: usize +} + +log_int(n): + if n < cached_int.len(): cached_int[n] + else if n == 0: -inf + else: ln(n as f64) + +log_half(n): + if n < cached_half.len(): cached_half[n] + else: ln(n as f64 + 0.5) +``` + +Then cap cache growth at a configurable threshold, such as: + +```text +2^16, 2^20, 2^22, unlimited +``` + +The first implementation should be private and compile-time or test-configurable. Do not expose a public API until the speed/memory phase diagram is known. + +Thresholds should be chosen by memory budget, not aesthetics: + +```text +cache_bytes ≈ 2 * threshold * sizeof(f64) +2^20 entries ≈ 16 MiB +2^22 entries ≈ 64 MiB +2^24 entries ≈ 256 MiB +``` + +For the default library mode, prefer the smallest threshold that preserves speed on current benchmarks. For a Hutter-specific memory-first mode, a lower threshold is acceptable if total RSS stays inside the 10 GB envelope and the time penalty remains under the 50-hour bound. + +### Why this is mathematically valid + +The cached value is exactly the same expression currently inserted into the cache: + +```text +(n as f64).ln() +(n as f64 + 0.5).ln() +``` + +Therefore, above-threshold direct computation should be semantically identical modulo libm determinism of the same expression. Archive parity is plausible and must be tested. + +### Implementation caution + +Do not insert an unpredictable branch at every hot arithmetic site if avoidable. Prefer passing a small `LogLookup` object with `#[inline(always)]` accessors, and keep the cached fast path branch simple. Audit all direct `log_int[...]` and `log_half[...]` uses. + +### Expected impact + +- **Reduces**: `S(n)` from unbounded cache memory to `O(threshold)`. +- **May increase**: `W(n)` through direct `ln` calls for high counts. +- **Hutter relevance**: mandatory if CTW/FAC-CTW is used on enwik9-scale streams. + +### Acceptance + +- Exact archive parity on small and medium CTW/neural-mixture runs if possible. +- RSS decreases for large prefixes when threshold is below observed root visits. +- Runtime penalty quantified. A memory-first mode can be accepted even if slower; a default change requires a tolerable speed/RSS tradeoff. +- CTW memory reports should separate arena memory from shared log-cache memory, otherwise the improvement can be hidden by other state. + +## P0 track: PPMD probability-query interface + +### Files + +```text +crates/infotheory/src/backends/ppmd.rs +crates/infotheory/src/compression/mod.rs +``` + +### Current implementation + +`PpmdModel::ensure_pdf_inner` computes a full byte distribution: + +```text +lower = uniform[256] +for ord in 0..=max_order: + key = context_key(ord) + if context exists: + lower = interpolate_context(ctx, lower) +normalize lower +``` + +`interpolate_context` writes a fresh `[f64; 256]`-sized array for each active context.

There are two possible designs: + +1. **Exact dense-equivalent query**: account for flooring/renormalization exactly. This may require knowing how many symbols fall below `PDF_MIN`, which may force more work. +2. **Unfloored internal query mode**: explicitly change semantics and evaluate archive effects. This is model-changing and should not be called an implementation optimization. + +Before designing the final query path, measure how often flooring is actually active: + +```text +min_unfloored_probability +count(pdf[i] < PDF_MIN) +mass_added_by_flooring +normalization_factor_after_flooring +``` + +If flooring is effectively never active for the benchmark/corpus region, the exact query path is simple and high-confidence.

The PPMD work accepted for production in this tranche is therefore the rolling suffix-key, map-entry tightening, and in-place interpolation work; the next high-confidence implementation item should move to CTW bounded/exact log lookup. ### 4.

The thread-local cache stores `log_int` and `log_half` up to the maximum visit count. At enwik9 scale, two `f64` arrays of length `n` are already about 16 GB before CTW arena state.

Rolling suffix keys are valid, but `PpmdModel::ensure_pdf_inner` also rebuilds dense 256-entry arrays across all active orders whenever a caller often needs only one symbol probability or a binary interval mass. The stronger direction is a probability-query interface that avoids dense PDF/CDF materialization when the coder/loss does not require it. -3. **RWKV7's next memory/time work should target TBPTT replay workspace churn before exotic kernels**.

Reusing this workspace and freeing it after the final full-train window is a more direct `A(n)/Q(n)/S(n)` target. -4. **Expert marginal utility must be measured explicitly**. Hutter-relevant optimization is not “make every expert faster”; it is “maximize compressed bits saved per byte of memory, second of CPU, and byte of program/model description.” A costly expert that contributes little marginal code-length improvement should be pruned, scheduled sparsely, or made optional before being hand-optimized. +1. **CTW's shared log cache asymptotic memory problem is addressed for this branch scope**.

It is deliberately not a permanent design spec. Its purpose is to keep optimization work scientifically grounded, Hutter-relevant, and resistant to seductive but low-yield micro-tuning. - -The current branch state materially changes the prioritization: - -1. **CTW's shared log cache asymptotic memory problem is addressed for this branch scope**. The bounded exact log-cache work landed, the hot-prefix sweep was completed, and depth `12` is the current chosen default. CTW should now be treated as done for this tranche unless later validation uncovers a new issue. -2. **PPMD's rolling suffix key and exact-entry update work landed, while sparse/exact query routing was investigated and rejected under the current representation**. Further PPMD work is now a later representation question, not the active branch target. -3. **RWKV7's next memory/time work should target TBPTT replay workspace churn before exotic kernels**. Fixed-shape GEMV specialization is plausible, but the current online TBPTT path still allocates replay-local vectors, per-step PDF vectors, traces, checkpoints, full gradient state, and recurrent gradient state per segment flush. Reusing this workspace and freeing it after the final full-train window is the active `A(n)/Q(n)/S(n)` target for this branch. -4. **Expert marginal utility still matters, but it is not the immediate branch task**. Ablation remains important for later resource-MDL decision-making, yet it is intentionally out of scope until the current optimization tranche is satisfactorily implemented. -5. **AC inlining and binary decode are now guardrail knobs, not the main research frontier**. They should remain in the benchmark matrix, but further AC work is lower priority unless a new profile contradicts the current evidence. - -## Hutter-aware objective - -For exact implementation optimizations, the predictive distribution and entropy coder semantics should be preserved. For model-changing experiments, the relevant objective is a resource-bounded MDL score, not raw archive size alone. - -Useful decomposition: - -```text -W(n): semantic and implementation arithmetic per byte -Q(n): copied bytes / memory traffic per byte -A(n): allocation events / allocator pressure per byte -S(n): live state size / peak RSS / cache footprint -B: release binary/program/model size after stripping/UPX when relevant -L(n): compressed codelength/archive bytes for the target corpus -``` - -For a Hutter-like candidate, think in terms of: - -```text -J(candidate) = - archive_bytes - + program_and_model_description_bytes - + hard penalties for time, RAM, disk, and decompression failures - + local soft penalties used only for search/ranking -``` - -The implementation tracks in this document should reduce one or more of `W/Q/A/S/B` while preserving `L(n)` exactly or nearly exactly. The model-science tracks may intentionally change `L(n)`, but then they must improve the measured resource frontier rather than merely be “interesting.” - -## Hutter feasibility gates - -The Hutter Prize resource envelope changes which optimizations are rational. For enwik9-scale work, the hard constraints imply: - -```text -input bytes: 1_000_000_000 -time limit: 50 hours -minimum throughput: ~5_556 bytes/s, before decompression/verification overhead -RAM limit: 10 GB -disk limit: 100 GB -target archive: < 110 MB to beat the current record class -``` - -The current 10 MB neural-mixture timing is not obviously time-infeasible under linear extrapolation, but its memory curve is the dangerous term. A 2.6 GiB RSS at 10 MB is already too close to the RAM limit if any major component grows linearly or superlinearly. Therefore the immediate Hutter-relevant question is: - -```text -Can the best compression-effective mixture be made sublinear/bounded enough in memory -while preserving most of its codelength advantage? -``` - -Every proposed optimization should be classified into one of four buckets: - -1. **Feasibility fix**: changes an impossible asymptotic or large constant that blocks enwik9-scale execution. -2. **Frontier improvement**: improves archive/time/RSS Pareto position on verified prefixes. -3. **Search enabler**: makes future model/tuner exploration cheaper without degrading compression. -4. **Cosmetic/local micro-win**: does not change feasibility or the Pareto frontier; deprioritize. - -The first two buckets are the only default priorities for Hutter progress. Search enablers are valuable when they unlock many evaluations. Cosmetic/local wins should be kept only if they are simple, exact, and non-invasive. - -## Evidence baseline - -The current `configs/bench/two.json` neural mixture is: - -```text -ctw(depth=32) -ppmd(order=12, memory_mb=256) -rosaplus(max_order=-1) -match -rwkv7(hidden=64,layers=1,intermediate=64,ranks=16,early full training, long inference tail) -``` - -Representative measured/profile facts: - -- **Neural mixture compression is strong but slow**: for 262144 bytes, neural mixture archive size is around `67454` bytes, versus CTW around `80004` and RWKV around `137010`. -- **Neural mixture runtime is expert-bound**: the neural combiner itself is around 1% self-time in the cited profile; CTW, RWKV, PPMD, and ROSA dominate. -- **Large-prefix memory is expert-state dominated**: 10 MB neural mixture RSS in the current checked-in data is around 2.6 GiB. -- **RWKV standalone RSS is low for the tiny config**, but its arithmetic and training replay are significant. -- **CTW standalone memory and time grow materially**, and its hidden shared-log-cache term is asymptotically dangerous at enwik9 scale. - -Representative 262144-byte neural-mixture compression self-time: - -```text -CtEngine::predict_one ~16.05% -rwkv7::Model::forward_with_sink ~15.74% -rwkv7::Model::accumulate_token_step_gradients ~10.29% -exp ~9.61% -CtEngine::update_prepared ~6.35% -PpmdModel::ensure_pdf_inner ~5.22% -RosaPlus::fill_probs_for_last_bytes ~4.10% -PpmdModel::update ~3.17% -RosaPlus::train_byte ~2.80% -rwkvzip::Compressor::logits_to_pdf ~1.96% -RatePdfPredictor::prepare_cached_cdf_fast_bitwise ~1.77% -NeuralMixCore::compute_context_mixtures ~1.03% -MatchModel::ensure_pdf_inner ~1.02% -``` - -Important current-code facts verified in the second pass: - -- `PpmdModel::context_key(ord)` hashes the suffix from scratch, and `PpmdModel::ensure_pdf_inner` rebuilds dense 256-entry distributions order by order. -- `MixturePredictor::ac_step_bitwise` already uses CTW's bitwise prepared path, and for several non-CTW experts calls `prepare_cached_cdf_fast_bitwise`, which still materializes full CDFs. -- `CtwPredictor::bit_prob_one_msb` already calls `FacContextTree::predict_one`, and `CtwPredictor::update_bit_msb` already calls `update_predicted`.

For hot expert changes, target at least 1-2% whole-subject improvement or a clear allocation/RSS win. -- **Memory**: for Hutter-scale asymptotic fixes, an optional mode can be accepted even with speed cost if it changes the feasibility class. -- **Binary size**: any specialization that increases text size must report stripped and optionally UPX-compressed binary deltas. - -### Model-changing or compute-allocation experiments - -Use these for expert pruning, approximate scheduling, changed floating semantics, or altered probability models: - -- **Primary**: archive bytes and decompression correctness. -- **Secondary**: time, RSS, temp disk, binary/model bytes. -- **Decision metric**: accept only if the Pareto frontier improves.

CTW update/revert paths call this with visit counts derived from `root_visits`. - -At `n = 1_000_000_000`, two `f64` arrays are about: - -```text -2 * 8 * n = 16 GB -``` - -That is already beyond the Hutter RAM limit before nodes, segments, experts, neural state, entropy coder state, and OS overhead. Therefore this is not a micro-optimization. It is a feasibility issue. - -### Hypothesis - -Replace unbounded direct slices with a bounded exact lookup abstraction: - -```text -LogLookup { - cached_int: &[f64], - cached_half: &[f64], - cache_limit: usize -} - -log_int(n): - if n < cached_int.len(): cached_int[n] - else if n == 0: -inf - else: ln(n as f64) - -log_half(n): - if n < cached_half.len(): cached_half[n] - else: ln(n as f64 + 0.5) -``` - -Then cap cache growth at a configurable threshold, such as: - -```text -2^16, 2^20, 2^22, unlimited -``` - -The first implementation should be private and compile-time or test-configurable. Do not expose a public API until the speed/memory phase diagram is known. - -Thresholds should be chosen by memory budget, not aesthetics: - -```text -cache_bytes ≈ 2 * threshold * sizeof(f64) -2^20 entries ≈ 16 MiB -2^22 entries ≈ 64 MiB -2^24 entries ≈ 256 MiB -``` - -For the default library mode, prefer the smallest threshold that preserves speed on current benchmarks. For a Hutter-specific memory-first mode, a lower threshold is acceptable if total RSS stays inside the 10 GB envelope and the time penalty remains under the 50-hour bound. - -### Why this is mathematically valid - -The cached value is exactly the same expression currently inserted into the cache: - -```text -(n as f64).ln() -(n as f64 + 0.5).ln() -``` - -Therefore, above-threshold direct computation should be semantically identical modulo libm determinism of the same expression. Archive parity is plausible and must be tested. - -### Implementation caution - -Do not insert an unpredictable branch at every hot arithmetic site if avoidable. Prefer passing a small `LogLookup` object with `#[inline(always)]` accessors, and keep the cached fast path branch simple. Audit all direct `log_int[...]` and `log_half[...]` uses. - -### Expected impact - -- **Reduces**: `S(n)` from unbounded cache memory to `O(threshold)`. -- **May increase**: `W(n)` through direct `ln` calls for high counts. -- **Hutter relevance**: mandatory if CTW/FAC-CTW is used on enwik9-scale streams. - -### Acceptance - -- Exact archive parity on small and medium CTW/neural-mixture runs if possible. -- RSS decreases for large prefixes when threshold is below observed root visits. -- Runtime penalty quantified. A memory-first mode can be accepted even if slower; a default change requires a tolerable speed/RSS tradeoff. -- CTW memory reports should separate arena memory from shared log-cache memory, otherwise the improvement can be hidden by other state. - -### Implementation status: bounded exact lookup accepted - -Implemented in `crates/infotheory/src/backends/ctw.rs`. - -design: - cached-prefix and bounded-fallback KT log access are now split again - `CachedLogs` keeps the under-threshold hot path on direct unchecked slice reads - `BoundedLogs` is used only once visits exceed the cap - shared CTW cache growth is capped by a private compile-time limit - accepted default cap is `2^24` entries, approximately 256 MiB for the two f64 caches - above-cap values compute the exact same expressions directly: - `ln(n as f64)` - `ln(n as f64 + 0.5)` - the first implementation remains private/test-configurable, as intended - -coverage: - all CTW/FAC-CTW update, prepared-update, revert, and FAC byte fast paths route - through the shared bounded cache machinery - the under-threshold fast path is still monomorphized on direct cached slices - test-only scoped limits force fallback at tiny thresholds - guardrails assert bounded logical cache length and separated log-cache memory reporting - `FacContextTree::memory_usage_breakdown()` now separates: - tree bytes - shared log-cache bytes - shared history bytes - -validation: - `cargo fmt --all -- --check` - `cargo test -p infotheory --no-default-features --features backend-ctw backends::ctw::tests:: --locked` - `cargo test -p infotheory --features all-backends compression::tests::roundtrip_rate_ac_ctw --locked` - `cargo test -p infotheory --features 'cli all-backends' --test cli_commands cli_compression_backend_json_roundtrips_rate_ac_ctw --locked` - `cargo test -p infotheory --no-default-features --features backend-ctw --test oracle_tests ctw_matches_theoretical_markov_entropy --locked` - `RUSTFLAGS='-D warnings' cargo check -p infotheory --no-default-features --features backend-ctw --locked` - `RUSTFLAGS='-D warnings' cargo check -p infotheory --no-default-features --features 'cli backend-ctw backend-mixture' --locked` - `RUSTFLAGS='-D warnings' cargo check -p infotheory --no-default-features --features 'tuner backend-ctw' --locked` - `git diff --check` - -current caveat: - lower defaults such as `2^20`, `2^21`, and `2^23` were measured and rejected for - the default mode because they introduced about 4-6% CTW `h` regressions on the - current 10 MB benchmark corpus when the accessor abstraction stayed on the hot path - or the threshold was crossed too early - with the accepted `2^24` cap plus the cached/bounded split: - 10 MB CTW `h` baseline/current on CPU 11 was about `161.9s -> 163.8s` (`+1.14%`) - 10 MB CTW `compress` was about `181.91s -> 182.41s` (`+0.28%`) - 10 MB CTW `decompress` was about `182.28s -> 182.83s` (`+0.30%`) - 20 MB CTW `h` was about `350.26s -> 356.20s` (`+1.70%`) while RSS fell - from about `1,027,124 KiB` to `976,484 KiB` (`-4.93%`) - this is the accepted default-mode compromise for now: bounded Hutter-feasible - log-cache memory without the earlier large current-suite slowdown - -## P0 track: PPMD probability-query interface - -### Files - -```text -crates/infotheory/src/backends/ppmd.rs -crates/infotheory/src/compression/mod.rs -``` - -### Current implementation - -`PpmdModel::ensure_pdf_inner` computes a full byte distribution: - -```text -lower = uniform[256] -for ord in 0..=max_order: - key = context_key(ord) - if context exists: - lower = interpolate_context(ctx, lower) -normalize lower -``` - -`interpolate_context` writes a fresh `[f64; 256]`-sized array for each active context.

The table should explicitly mark each expert as: - -```text -keep/default -keep/optional speed-tier -bounded-state redesign required -drop or defer -needs longer-prefix evidence -``` - -## P1 track: CTW representation phase diagram - -### Files - -```text -crates/infotheory/src/backends/ctw.rs -``` - -### Current implementation - -CTW stores explicit nodes through `HOT_PREFIX_DEPTH` and compressed unary/path segments deeper in the tree. This is the central speed/memory representation tradeoff. - -### Hypothesis - -Sweep `HOT_PREFIX_DEPTH` locally: - -```text -6, 8, 10, 12, 14 -``` - -and measure: - -```text -CTW standalone h/compress/decompress -neural mixture h/compress/decompress -RSS -archive bytes -prepared path case distribution -``` - -Also instrument: - -```text -PreparedEnd frequencies -prepared_steps.len() -node versus segment steps -has_sibling frequency -segment span distribution -``` - -### Expected impact - -- **Trades**: `W(n)` against `S(n)`. -- **May reveal**: whether current `HOT_PREFIX_DEPTH = 10` is on the Pareto frontier. -- **May guide**: targeted CTW branch specializations. - -### Acceptance - -Do not change the default from one benchmark point. Require a phase diagram across at least 262144, 1 MiB, 4 MiB, and 10 MB. If archive bytes differ due floating-order effects, treat as a model/numerical change and evaluate resource frontier rather than claiming exact parity. - -## P2 track: PPMD compact continuation storage - -### Files - -```text -crates/infotheory/src/backends/ppmd.rs -``` - -### Current implementation - -Each context stores: - -```rust -counts: Vec<(u8, u16)> -total: u32 -``` - -For many contexts with few continuations, a separate `Vec` allocation per context is likely expensive in both allocator pressure and memory overhead. - -### Hypothesis - -Use an inline-small representation: - -```text -TinyCounts { - len: u8 - inline: [(u8, u16); N] - spill: Option> -} -``` - -Test `N = 2, 4, 6`. Do this after probability queries and suffix keys, because those may change the profile enough to alter the best storage design. - -### Correctness invariant - -The count multiset, `total`, rescale behavior, and interpolation distribution must match the current representation exactly. - -### Expected impact - -- **Reduces**: `S(n)` and `A(n)`. -- **May reduce**: `W(n)` through locality. -- **Risk**: branchier code and larger context structs if `N` is wrong. - -## P2 track: exact interval/probability query API for other experts - -### Files - -```text -crates/infotheory/src/compression/mod.rs -crates/infotheory/src/backends/match_model.rs -crates/infotheory/src/backends/rosaplus.rs -crates/infotheory/src/backends/rwkvzip/mod.rs -``` - -### Current implementation - -`MixturePredictor::ac_step_bitwise` has three modes: - -```text -0: CTW bitwise prepared prediction/update -2: expert cached CDF branch probability -1: fallback local PDF-derived CDF row -``` - -For non-CTW byte experts, the model state is not updated until the full byte is known. Therefore exact byte-distribution interval queries are valid if they reproduce the same distribution. - -### Match - -Match has the simplest exact interval mass. Its distribution is uniform or a single predicted-byte spike over a uniform background: - -```text -mass([lo, hi)) = rest * len + spike_mass_if_predicted_inside -``` - -This can avoid `pdf[256]` and `cdf[257]` construction in bitwise mode. The whole-suite gain may be small because Match is not a major self-time contributor, so implement only if the abstraction is needed for PPMD/ROSA anyway. - -### ROSA+ - -ROSA interval mass may be possible from LM alphabet/count structures, but it is more invasive. Do not start here. First measure ROSA marginal utility and identify whether `fill_probs_for_last_bytes` is a dominant cost on compression/decompression, not only on `h`. - -### RWKV7 - -RWKV needs logits over the full vocabulary for the softmax denominator. Interval queries cannot avoid the LM-head logits. A direct logits-to-CDF path may save a `f64` PDF pass, but `rwkvzip::Compressor::logits_to_pdf` is only about 2% self-time in the cited profile, so this is not a P0 track. - -### Acceptance - -For each expert: - -```text -all binary prefix masses == dense CDF reference -archive parity -decompression roundtrip -whole neural-mixture signal non-negative -``` - -## P2 track: RWKV7 fixed-shape GEMV specialization - -### Files - -```text -crates/infotheory/src/backends/fixed_gemv.rs -crates/infotheory/src/backends/rwkvzip/rwkv7/kernel.rs -crates/infotheory/src/backends/rwkvzip/rwkv7/model.rs -``` - -### Current implementation - -`gemv_avx` is generic.

Preserve accumulation order as much as possible. Do not use FMA or reordered reductions unless archive parity still holds. - -### Why this is P2, not P0 - -It may improve `W(n)`, but it increases code size and may perturb floating behavior.

Added `BytePrefix` as a session type, which uses the binary tree to decompose and provide per-bit probabilities.

556524301d934f5f5833a345e94a28789e42c5f7 Mon Sep 17 00:00:00 2001 From: Noah Cashin Date: Sat, 23 May 2026 21:22:07 -0400 Subject: [PATCH 137/172] Implement begin_stream hooks for stream restarts - Add `begin_stream` hooks to `RateBackendSession` and `RateBackendBitSession` - Update `MixtureRuntime` to route restarts via `begin_fresh_stream`. Mixture weights and cumulative log losses correctly reset to their priors, while delegating to each expert's supported initialization behavior (preserving fitted state on resettable experts while hard-restarting non-resettable ones). - Harden the ZPAQ memory lifecycle by guaranteeing a sequential `drop(take())` of the underlying streaming context prior to reallocation. - Update tests accordingly --- crates/infotheory/src/api/context.rs | 11 + crates/infotheory/src/backends/zpaq_rate.rs | 72 ++++--- crates/infotheory/src/mixture.rs | 221 +++++++++++++++++++- crates/infotheory/tests/api_surface.rs | 111 +++++++++- crates/infotheory_py/src/lib.rs | 29 ++- python/tests/test_bit_session.py | 41 ++++ python/tests/test_generation.py | 61 ++++++ 7 files changed, 513 insertions(+), 33 deletions(-) diff --git a/crates/infotheory/src/api/context.rs b/crates/infotheory/src/api/context.rs index 996f0c6d..9f09d513 100644 --- a/crates/infotheory/src/api/context.rs +++ b/crates/infotheory/src/api/context.rs @@ -315,6 +315,17 @@ impl RateBackendSession { .map_err(InfotheoryError::runtime) } + /// Start a new stream while preserving each backend's semantic contract. + /// + /// Backends that support frozen-reset semantics will restart via + /// `reset_frozen`.

prior commits: - AIQI byte-packed validation now treats observations plus reward as one percept segment instead of requiring each to be byte-aligned separately. - ZPAQ update_and_score now reports raw compressor bit growth again in zpaq_rate.rs, so the probability floor stays confined to probability-query APIs instead of capping metric paths. --- crates/infotheory/src/aixi/agent.rs | 15 ++++----

ZpaqRateModel::fill_log_probs is now actually read-only with respect to pending speculative state - RateBackendBitSession::from_backend now rejects pathological BitStreamSemantics::BytePacked sessions cleanly instead of silently admitting ZPAQ into the O(256 * H) fallback path - added a separate capability, supports_efficient_byte_packed_bit_sessions --- crates/infotheory/src/api/context.rs | 6 ++

It is +intentionally independent of \texttt{docs/infotheory-tuner-v1.tex}; the tuner +use case is an instantiation of the model, not the definition of the model. + +The core object is a finite-action, finite-observation, finite-label +controller over a certified same-task bridge. The bridge defines admissible +actions, observations, one-step rewards, finite-horizon labels, label decoding, +and task identity. \Warm{} learns a conditional return-label law +\[ +\widehat p(\ell\mid h,a), +\] +not an action-cloning policy \(\pi_T(a\mid h)\). This is the structural sense +in which it is AIQI-like: it performs direct induction over action-conditional +return distributions rather than imitating the teacher's realized action +sequence. + +A teacher is any controller or policy that can produce realized transitions +under the same compiled bridge contract. Its family name is not part of +admissibility: MC-AIXI, discounted AIQI, \Warm{} itself, a hand-coded policy, +a random policy, or a future Infotheory controller are all valid teachers if +their traces satisfy the contract below. + +The Rust/controller name \Warm{} is historical for the tuner exact-\(\Jh\) +instantiation. Mathematically, the core is bridge-parametric exact return-law +warmstart. In the direct integer-reward bridge, labels decode to \(H\)-step +reward sums. In the tuner bridge, labels decode to exact \(\Jh\) incumbent +improvement. This document preserves the tuner theorem boundary by treating +that bridge as a separately certified instantiation. + +\section{Compiled Task Contract} +\label{sec:task} + +\begin{definition}[Certified same-task bridge] +A certified same-task bridge is a tuple +\[ +\Bridge=(\Act,\Ospace,\Rspace,\Lab,\Vlab,\Omega_R,\Omega_{\Lab}, +\operatorname{Label}_H,\sigma) +\] +where \(\Act\), \(\Ospace\), and \(\Rspace\) are finite action, +observation, and one-step reward domains; \(\Lab\) is a finite label +alphabet; \(\Vlab:\Lab\to\mathbb{R}\) is the exact semantic value decoder; +\(\Omega_R\) and \(\Omega_{\Lab}\) are injective finite encoders for rewards +and labels; \(\operatorname{Label}_H\) deterministically maps every realized +same-task \(H\)-window to a label in \(\Lab\); and \(\sigma\) is the bridge +task fingerprint. +\end{definition} + +\Warm{} only requires the bridge to provide finite, same-task, exactly +decodable labels. The direct standalone bridge uses +\[ +\operatorname{Label}_H((a_j,o_j,r_j)_{j=i}^{i+H-1}) += +\sum_{j=i}^{i+H-1}r_j +\] +and \(\Vlab(\ell)=\ell\). Other certified bridges may use different exact +label semantics without changing the warmstart predictor or policy. + +\begin{definition}[Compiled warm-start task] +A compiled warm-start task is a tuple +\[ +M=(\Bridge,H,B,N,P,\rho) +\] +with the following components: +\begin{itemize} + \item a certified same-task bridge \(\Bridge\); + \item a finite return horizon \(H\ge1\); + \item an exact return-label alphabet size + \(B=|\Lab|\ge1\); + \item a label phase period \(N\ge H\); + \item a finite-alphabet predictive backend \(P\) supporting strict frozen + history conditioning; + \item a deterministic seed \(\rho\). +\end{itemize} +\end{definition} + +For the direct integer-reward standalone bridge, the return-label alphabet must +be exact for a dense nonnegative reward interval. Thus \(B-1\) must be +divisible by \(H\), and the reward domain is derived from \(H\), \(B\), and +\(b_R\) by +\[ +r_{\min}=0, +\qquad +r_{\max}=\frac{B-1}{H}, +\qquad +\Rspace=\{0,\dots,r_{\max}\}. +\] +The channel bit width must represent every reward in \(\Rspace\). This +choice makes the \(H\)-step return set exactly +\(\{0,\dots,B-1\}\). Slack return bins are non-conforming: they would create +labels with no exact direct-bridge return preimage and are rejected by the +compiled warm-start contract. Signed or non-identity reward channels require +an explicit future contract or an externally certified bridge such as the +tuner bridge in Section~\ref{sec:tuner-bridge}. + +At step \(t\ge1\), the controller emits \(a_t\in\Act\), then receives +\((o_t,r_t)\in\Ospace\times\Rspace\). The realized history before choosing +\(a_t\) is +\[ +h_{ \ + --teacher \ + --out +\end{verbatim} +The target planner run must use \texttt{aiqi\_warmstart\_exact\_jh}. The +teacher planner run may use any CLI-executable planner controller. The export +command: +\begin{enumerate} + \item compiles both planner-run documents through the canonical spec + pipeline; + \item verifies that target and teacher have identical planner interface + values and identical canonical environment JSON; + \item executes the teacher controller for its configured learning and + evaluation cycles; + \item records realized transitions after each action; + \item rejects the run if fewer than \(H\) transitions were produced; + \item builds the target standalone teacher contract; + \item validates the resulting artifact by constructing the target + \Warm{} agent from it; + \item writes pretty canonical teacher JSON to \texttt{--out}. +\end{enumerate} +This realizes the offline-to-online path: any controller can act as teacher, +and the resulting artifact initializes a \Warm{} student for the target task. + +The reproducibility CLI also exposes: +\begin{verbatim} +infotheory warmstart teacher from-jsonl \ + --target --jsonl --out + +infotheory warmstart teacher merge \ + --target --out \ + --teacher --teacher ... +\end{verbatim} +The first command implements the deterministic telemetry converter from +Section~\ref{sec:telemetry}. The second performs the deterministic +same-contract trace union defined there and validates the merged result by +constructing the target student. + +\section{Online Trace Refresh} +\label{sec:refresh} + +During online deployment, \Warm{} can export its own live same-task trace after +at least \(H\) transitions. The live trace is not itself a teacher artifact; it +becomes teacher data only when it is wrapped under the unchanged target +contract, merged into the teacher dataset, and validated by the same full +dataset gate used for ordinary teacher artifacts. A refresh wrapper may then +reinitialize the student from the merged dataset. + +A bounded refresh loop is specified by an initial teacher dataset +\(\Teach^{(0)}\), a maximum number of refresh rounds \(R\), and a finite run +budget per round. Round \(r\) builds \(W^{(r)}\) from \(\Teach^{(r)}\), executes +it on the same compiled bridge, extracts a live trace \(\tau^{(r)}\) if one has +at least \(H\) transitions, and sets +\[ +\Teach^{(r+1)} += +\operatorname{Merge}(\Teach^{(r)},\tau^{(r)}). +\] +\(\operatorname{Merge}\) is the deterministic trace-content union of +Section~\ref{sec:teacher-artifact}. The loop stops after \(R\) rounds, or +earlier if no admissible live trace is produced. + +\begin{proposition}[Refresh trace payload admissibility] +If a live \Warm{} trace of length at least \(H\) is produced by a target +runtime that validates every emitted action, observation, and reward against +the compiled target bridge, then wrapping that trace under the unchanged target +contract yields transition payloads whose complete horizon windows are +admissible teacher labels for that same target contract. +\end{proposition} + +\begin{proof} +Every recorded action, observation, and reward has already passed the target +runtime's transition validator. Each label is the deterministic \(H\)-step sum +of rewards in that same trace. The trace length premise gives at least one +complete delayed-label window, and the unchanged wrapper contract supplies the +same fingerprint, interface fields, horizon, phase period, and provenance +fields required by Definition~\ref{def:admissible-teacher}. Therefore the +wrapped live trace can pass the teacher-artifact validator as part of the +merged dataset. +\end{proof} + +Refresh is a data mechanism, not a monotonic-improvement theorem. It improves +the theorem-facing local bound only to the extent that the refreshed predictor +is closer to the target conditional label law on visited histories. + +\begin{theorem}[Conditional local refresh improvement] +Fix a history \(h\) and suppose two same-bridge students differ only in their +teacher artifact: an initial student \(W_0\) and a refreshed student \(W_1\). +If, for every action, +\[ +\|\widehat p_{W_1}(\cdot\mid h,a)-p(\cdot\mid h,a)\|_{\TV} +< +\|\widehat p_{W_0}(\cdot\mid h,a)-p(\cdot\mid h,a)\|_{\TV}, +\] +then the local finite-horizon value-error bound of +Theorem~\ref{thm:tv-robustness} is strictly smaller for \(W_1\) than for +\(W_0\) at \(h\). +\end{theorem} + +\begin{proof} +The bound in Theorem~\ref{thm:tv-robustness} is monotone in the uniform +total-variation radius. A strict decrease for every action gives a strict +decrease of the supremum radius at \(h\), and therefore a strict decrease of +the displayed value-error bound. +\end{proof} + +For bridges with monotone incumbent semantics, such as the tuner exact-\(\Jh\) +bridge, the bridge may prove additional best-so-far or objective-monotonicity +claims. Those claims belong to the bridge specification; they are not implied +by refresh alone for arbitrary environments. + +\section{Core Theorems} +\label{sec:theorems} + +Let \(p_t(\ell\mid h,a)\) be the true conditional law of the exact +\(H\)-step return label at history \(h\) under action \(a\). Define +\[ +Q^\star_H(h,a)=\sum_{\ell\in\Lab}\Vlab(\ell)p_t(\ell\mid h,a). +\] +Let +\[ +D_G=\max_{\ell\in\Lab}\Vlab(\ell)-\min_{\ell\in\Lab}\Vlab(\ell). +\] +For the direct integer-reward bridge, \(D_G=Hr_{\max}-Hr_{\min}=Hr_{\max}\). + +\begin{theorem}[Exact greedy alignment] +If, at a greedy decision history \(h\), +\[ +\widehat p_t(\cdot\mid h,a)=p_t(\cdot\mid h,a) +\quad\text{for every }a\in\Act, +\] +then \Warm{} selects an action maximizing the true expected exact +\(H\)-step return \(Q^\star_H(h,a)\), with deterministic lowest-index +tie-breaking. +\end{theorem} + +\begin{proof} +Under the premise, \(\widehat Q_H(h,a)=Q^\star_H(h,a)\) for every action. +The implemented rule chooses the lowest-index maximizer of these same values. +\end{proof} + +\begin{theorem}[Total-variation robustness] +\label{thm:tv-robustness} +If +\[ +\sup_{a\in\Act} +\|\widehat p_t(\cdot\mid h,a)-p_t(\cdot\mid h,a)\|_{\TV} +\le \delta, +\] +then the greedy \Warm{} action \(\hat a\) satisfies +\[ +Q^\star_H(h,a^\star)-Q^\star_H(h,\hat a)\le 2D_G\delta, +\] +where \(a^\star\) is any true optimal action. +\end{theorem} + +\begin{proof} +For any bounded function with range diameter \(D_G\), expectation changes by +at most \(D_G\) times total variation. Thus +\[ +|\widehat Q_H(h,a)-Q^\star_H(h,a)|\le D_G\delta +\] +for every action. Since \(\hat a\) maximizes \(\widehat Q_H\), +\[ +Q^\star_H(h,a^\star) +\le \widehat Q_H(h,a^\star)+D_G\delta +\le \widehat Q_H(h,\hat a)+D_G\delta +\le Q^\star_H(h,\hat a)+2D_G\delta. +\] +\end{proof} + +\begin{corollary}[Teacher action-gap preservation] +If the teacher value \(\QT\) has a unique greedy action \(a_T\) at \(h\) and +\[ +\sup_{a\in\Act}|\widehat Q_W(h,a)-\QT(h,a)|<\Delta_T(h)/2, +\] +then the greedy warmstart action equals \(a_T\). In particular, the condition +holds whenever +\[ +\sup_{a\in\Act}\|\widehat p_W(\cdot\mid h,a)-\PT(\cdot\mid h,a)\|_{\TV} +\le\delta +\quad\text{and}\quad +D_G\delta<\Delta_T(h)/2. +\] +\end{corollary} + +\section{Tuner Bridge Instantiation} +\label{sec:tuner-bridge} + +The tuner bridge instantiates the generic reward \(r_t\) as exact improvement +in the deployable two-part objective: +\[ +\Jh(z;d)=8L_B(z)+\ell_H(z). +\] +For incumbent sequence \(b_t\), the exact reward is +\[ +r_t=\Jh(b_{t-1};d)-\Jh(b_t;d) +\] +after the bridge's finite reward encoder has certified representability and +injectivity. Therefore the \(H\)-step label telescopes: +\[ +G_i^{(H)} +=\sum_{j=i}^{i+H-1}r_j +=\Jh(b_{i-1};d)-\Jh(b_{i+H-1};d). +\] +This is the tuner theorem use case.
