LISA: A Learned Index Structure for Spatial Data
Summary: LISA applies learned indexing to spatial data: map 2D points to 1D keys, predict shards, and organize pages with local models. Lattice regression converts KNN to range queries and supports updates; experiments show storage and IO gains vs R-tree. (summarized by gpt-5-nano on Feb 09 2026)
