We can split ANN algorithms into three distinct categories; trees, hashes, and graphs. HNSW slots into the graph category. More specifically, it is a proximity graph, in which two vertices are linked based on their proximity (closer vertices are linked) — often defined in Euclidean distance. There is a significant leap in … Ver mais During graph construction, vectors are iteratively inserted one-by-one. The number of layers is represented by parameter L. The … Ver mais We will implement HNSW using the Facebook AI Similarity Search (Faiss) library, and test different construction and search parameters and see how these affect index performance. To initialize the HNSW index we … Ver mais E. Bernhardsson, ANN Benchmarks(2024), GitHub W.
