An Efficient and Accurate Method for Evaluating Time Series Similarity

Summary: FTSE accelerates threshold-based time-series similarity (e.g., LCSS, EDR) beyond DP and warp-limiting bounds like Sakoe-Chiba/Itakura. Swale generalizes epsilon-based scoring to arbitrary match rewards and gap penalties, yielding faster, more accurate evaluation across epsilon-threshold techniques.
