SPANN: A Highly-Efficient Billion-Scale Approximate Nearest Neighbour Search That’s 2× Faster Than the SOTA Method

A research team from Microsoft, Peking University, Tencent, and Baidu proposes SPANN, a simple but efficient memory-disk hybrid vector indexing and search system that guarantees both low latency and high recall and achieves a 2× speedup over the state-of-the-art nearest neighbour search (ANNS) solution while retaining the same recall quality and memory cost.
