A new research paper introduces CwA (Cluster with Auctions), a method that jointly learns a balanced database partition and a neural probing function for large-scale approximate nearest neighbor search. This approach optimizes search performance specifically for the query distribution, even when it differs from the database distribution. CwA achieves up to 4.7x higher throughput than existing state-of-the-art methods at equal recall, and its trained probing function outperforms competing deep neural methods in in-distribution settings.
