omop-emb

Embedding layer for OMOP CDM.

Installation

omop-emb now exposes backend-specific optional dependencies so installation can match the embedding backend you actually intend to use.

pip install "omop-emb[postgres]"
pip install "omop-emb[faiss]"
pip install "omop-emb[all]"

Notes:

• postgres installs the PostgreSQL/pgvector dependencies.
• faiss installs the FAISS-based backend dependencies. This currently only includes CPU support
• all installs both backend stacks for development or mixed environments.
• A plain pip install omop-emb installs the shared core package only.
• PostgreSQL-specific embedding dependencies are now optional, but omop-emb still requires some database backend for OMOP access and model registration.
• Non-PostgreSQL database backends have not yet been tested.

Extended documentation can be found here.

Project Roadmap

• Interface for postgres storage of vectors
• Interface for FAISS storage of embeddings
• Extensive unit testing
  • Backend testing
  • Corruption and restoration of DB testing
• Support non-Flat indices for each backend
• faiss GPU support
• pgvectorscale support
• Vector-quantisation for more efficient storage
