NeurIPS 2023 Competition Track: Big-ANN

This competition focuses on developing indexing data structures and search algorithms for practical settings of the Approximate Nearest Neighbor (ANN) or Vector search problem. The challenge has four tracks covering sparse, filtered, out-of-distribution and streaming variants of ANNs. These variants require adapted search algorithms and strategies with different tradeoffs.
