FAISS is a library for efficient similarity search over dense vectors when brute-force comparison becomes too expensive.
What it solves
Indexes can narrow candidate searches instead of comparing a query with every stored vector.
Why index choice matters
Different index families trade memory, build cost, speed, and recall.
In Abdullah’s work
FAISS is used in the multimodal recommender to retrieve nearest neighbors over the shared representation.
