Input Interface

Input Interface and Generic Signal Protocol

Generated with Grok Build: Grok 4.5 · xAI Imagine (/imagine)

LiquidCortex accepts generic numeric tensors only. Domain decoders belong in application code.

SparseBrain / EnsembleBrain Contract

Signal	Type	Constraints
Input u	CuVector{Float32}	length(u) == n_in for the brain/ensemble
inhibition	Real → Float32	Clamped to [0, MAX_INHIBITION] (3.0)
reflex_eta	Real → Float32	Learning rate override (default ETA)
reflex_signal	Real → Float32	Ensemble only; `

Defaults at construction: n_in=14, n_out=16 (SparseBrain / EnsembleBrain). Change both consistently when wiring a pipeline.

Constructing inputs

using CUDA

# zeros / ones / filled
u = CUDA.zeros(Float32, n_in)
u = CUDA.ones(Float32, n_in) .* 0.1f0

# from host
u = cu(Float32[0.1, 0.0, -0.2, ...])  # length must match n_in

# streaming: mutate in place each tick
u .= new_features  # still CuVector{Float32}
step!(brain, u; inhibition=stress)

Dimension errors

Mismatched length throws DimensionMismatch with expected vs actual sizes — fail fast rather than silent pad/truncate.

What Was Removed

Public API does not export:

• MarketPulse
• decode_market_pulse
• pulse_to_input

Former market- or mining-specific feature packs should be rebuilt in the consumer (e.g. strategy service) as plain Vector{Float32} / CuVector{Float32} feature vectors.

Reference LSM Contract

Signal	Type	Notes
inputs_vec	Vector{Float32} (host)	Length sets n_in on first lazy init
inhibit_val	Float32	Gain shrink: gain = 1 - 0.4 * inhibit_val
n_out	Int	Only applied on first lazy init

Returns host Vector{Float32} or CSV string via run_lsm_step_str.

Guidance for Arbitrary Time Series

1. Choose fixed n_in / n_out for the experiment.
2. Normalize features to a stable scale (package does not auto-scale).
3. Map operational stress → inhibition ∈ [0, 1] (or up to 3 if intentional).
4. Map discrete shocks → reflex_signal with magnitude > 0.1 when flash-learning is desired.
5. Read get_output / get_ensemble_output each tick or on a schedule for control / logging.
