Fast and Efficient Approximate Nearest Neighbor Search for High-Dimensional LLM Embeddings
This paper addresses both $k-Nearest Neighbor Graph (kNNG) construction on 1024-dimensional BGE-M3 embeddings and Maximum Inner Product Search (MIPS) on unnormalized Llama-3.2-8B features, and introduces a 1D presorting mechanism via Fast Linear Assignment Sorting (FLAS) prior to graph construction.
