The pgm-index

WebbWhy are learned indexes so effective?. In Proceedings of the 37th International Conference on Machine Learning (ICML). PMLR, 2024. In brief, these papers give the first mathematical proof that, under certain general assumptions on the input data, the PGM-index (website repository) is orders of magnitude more compressed than traditional indexes. WebbLearned index structures were first introduced in [10]. Several works on learned index structures followed [6, 7, 4, 9, 14, 13, 15, 12, 5, 11]. For example, PGM index [6], FITing tree [7], RadixS-pline [9] and ALEX [4] all investigate how to efficiently support inserts, provide better worst-case guarantees, and/or faster index construction.

In the (static) context of just predecessor and range queries these bounds turn out to be optimal. We call this learned index the _Piecewise Geometric Model index_ (PGM-index).
