In time series analysis, dynamic time warping (DTW) is an algorithm for measuring similarity between two temporal sequences, which may vary in speed. For instance, similarities in walking could be detected using DTW, even if one person was walking faster than the other, or if there were accelerations and decelerations during the course of an observation. DTW has been applied to t… WebOct 11, 2024 · The Dynamic Time Warping (DTW) distance measure is a technique that has long been known in speech recognition community.
