hnsw-rust - a fast HNSW implementation in Rust Technical Details hnsw-rust is a Rust implementation of The Hierarchical Navigable Small World (HNSW) algorithm. HNSW is a notable advancement in Approximate Nearest Neighbor (ANN) search in high-dimensional spaces, fundamentally altering our approach to these problems. The algorithm constructs a layered graph structure, where higher layers (less dense) are used for rapid global navigation, while lower layers (more dense) facilitate fine-grained loc...
