Dynamic time warping dtw algorithm
WebMar 2, 2024 · The Dynamic Time Warping (DTW) algorithm is one of the most used algorithm to find similarities between two time series. Its goal is to find the optimal global alignment between two time series by exploiting temporal distortions between them. DTW algorithm has been first used to match signals in speech recognition and music retrieval 1. WebThe function performs Dynamic Time Warp (DTW) and computes the optimal alignment between two time series x and y, given as numeric vectors. The "optimal" alignment minimizes the sum of distances between aligned elements. Lengths of x and y may differ.
