iDEC: Indexable Distance Estimating Codes for Approximate Nearest Neighbor Search

Summary: iDEC introduces an indexable distance-estimating-code framework extending LSH for ANN. It achieves O(n) index space and ~O(log n) query time, beating LSH on Hamming/edit distances with scalable in-memory ANN-H and linking EEC, LSH, and iDEC. (summarized by gpt-5-nano on Feb 09 2026)
