Locally Adaptive Dimensionality Reduction for Indexing Large Time Series Databases

Summary: APCA yields per-series, locally optimized segments of varying lengths for high-fidelity reconstruction. Index APCA on a multidimensional index with LB and a tight non-LB distance, enabling fast exact and approximate searches. (summarized by gpt-5-nano on Feb 09 2026)
