- [Approximate Nearest Neighbors (ANN)](https://vectordb.ever.works/items/approximate-nearest-neighbors-ann) — Algorithms and techniques for finding nearest neighbors in high-dimensional vector spaces with speed-accuracy trade-offs. ANN methods like HNSW, IVF, and DiskANN enable billion-scale vector search by sacrificing small amounts of recall for massive performance gains over exact search.
