Hierarchical Navigable Small Worlds (HNSW) | Pinecone

Demystifying and experimenting with HNSW for vector search.

Hierarchical Navigable Small Worlds (HNSW) Jump to section Foundations of HNSW Graph Construction Implementation of HNSW References Hierarchical Navigable Small World (HNSW) graphs are among the top-performing indexes for vector similarity search [1]. HNSW is a hugely popular technology that time and time again produces state-of-the-art performance with super fast search speeds and fantastic recall. Yet despite being a popular and robust algorithm for approximate nearest neighbors (ANN) searches, understanding how it works is far from easy. Note: Pinecone lets you build scalable, performant ve
