Trajectory Simplification: On Minimizing the Direction-based Error
Summary: Defines Min-Error for direction-preserving trajectory simplification (DPTS) under a fixed output size, removing reliance on user-specified tolerances by directly minimizing error. Proposes two exact algorithms and a 2-approximation algorithm; experiments on real datasets validate efficiency and accuracy. (summarized by gpt-5-nano on Feb 09 2026)
