Cluster with Auctions: The FAISS Team Teaches Vector Indexes to Learn From Queries
Summary
IVF-style vector search partitions data into clusters and probes a few per query, but almost every system assigns queries with the same function that partitioned the data. Cluster with Auctions (Meta AI, the FAISS lineage) jointly learns a balanced partition and a neural probing function: vectors are reassigned by a large-scale auction while the probe learns the live query distribution.
