Web4, Derivative Dynamic Time Warping Algorithm. As mentioned earlier, the DTW algorithm is roughly (wildly) according to the value of the Y-axis of the X-axis Warp variable, so that the Y-axis variables easily cause subtle changes in the singularity problem, as shown in FIG. WebDynamic time warping (DTW), which finds the minimum path by providing non-linear alignments between two time series, has been widely used as a distance measure for time series classification and clustering. However, DTW does not account for the relative importance regarding the phase difference between a reference point and a testing point.
