Efficient Non-Learning Similar Subtrajectory Search
Summary: Introduces the first exact O(mn) algorithm for similar subtrajectory search, improving over the O(mn²) barrier across WED, DTW, ERP, EDR, and Fréchet distances. Extensive experiments on three real datasets demonstrate substantial efficiency and effectiveness gains. (summarized by gpt-5.6-luna on Jul 24 2026)
