Indexable PLA for Efficient Similarity Search

Summary: Revisits PLA for time-series similarity search, with a PLA-space distance that lower-bounds Euclidean distance for exact pruning. Proposes an indexable PLA framework using these bounds, achieving strong pruning and faster search than APCA and CP. (summarized by gpt-5-nano on Feb 09 2026)
