Sim-Piece: Highly Accurate Piecewise Linear Approximation through Similar Segment Merging
Summary: Sim-Piece clusters similar PLA line segments to jointly encode them, minimizing group count to compact the PLA description and improve the space-vs-error tradeoff. Lightweight merging adds little overhead and yields >2x average compression vs prior PLA, enabling much higher accuracy at the same space. (summarized by gpt-5-mini on Feb 09 2026)
