WebAug 8, 2024 · FAISS uses binning and PQ (Product Quantization) to yield approximate answers quickly and requiring considerably less memory. So the score might bounce around because of this approximation. It's not even guaranteed to find all KNN because of the approximation (due to sampling of only some bins, I think). WebFAISS is nice for small to medium datasets, but it ends up having high memory requirements when things get too big. ...

http://ann-benchmarks.com/hnsw(faiss).html WebFaiss is a library for efficient similarity search and clustering of dense vectors. It contains algorithms that search in sets of vectors of any size, up to ones that possibly do not fit in RAM. It also contains supporting code for evaluation and parameter tuning. Faiss is written in C++ with complete wrappers for Python (versions 2 and 3).
