FTW: Fast Similarity Search under the Time Warping Distance

Summary: FTW: an exact DTW similarity-search method that guarantees no false dismissals by introducing a novel, highly effective pruning scheme exploiting time-warp invariance. Empirically prunes many candidates and achieves up to 222× speedup versus prior SOTA. (summarized by gpt-5-mini on Feb 09 2026)
