Efficient and robust approximate nearest neighbor search using Hierarchical Navigable Small World graphs

30 Mar 2016 Yu. A. Malkov D. A. Yashunin

We present a new approach for the approximate K-nearest neighbor search based on navigable small world graphs with controllable hierarchy (Hierarchical NSW, HNSW). The proposed solution is fully graph-based, without any need for additional search structures, which are typically used at the coarse search stage of the most proximity graph techniques...
