Maximum Inner Product is Query-Scaled Nearest Neighbor

Summary: Equates MIPS to query-scaled NNS without space transformations, enabling direct use of graph-based indexes and edge-pruning to eliminate redundant computations. Adds PSP to avoid large-norm solution clustering and AET to curb over-exploration, yielding ~35% speedup and 3x smaller indexes (deployed in Shopee). (summarized by gpt-5-mini on Feb 09 2026)
