WebJan 11, 2024 · Guidelines (outdated) When the dataset is around 1m vectors, the exhaustive index becomes too slow, so a good alternative is IndexIVFFlat. It still returns exact distances but occasionally misses a neighbor because it is non-exhaustive. Experiments from 2024. search time. 1-R@1. index size. index build time. Flat-CPU. WebJul 8, 2024 · The simplest implementation of the index in FAISS is the IndexFlatL2 index. It is an exact search index that encodes the vectors into fixed-size codes. As the name suggests it is an index that compares the L2 (euclidean) distance between vectors and returns the top-k similar vectors. During the search, all the indexed vectors are decoded ...
