WebJan 30, 2024 · In time series analysis, dynamic time warping (DTW) is one of the algorithms for measuring similarity between two temporal sequences, which may vary in speed. Fast DTW is a more faster method. I would like to know how to implement this method not only between 2 signals but 3 or more.

Suppose x is a time series that is constant except for a motif that occurs at some point in the series, and let us denote by x + k a copy of x in which the motif is temporally shifted by k timestamps, then DTWq(x, x + k) = 0.

WebJun 29, 2024 · The code fits time warping models with either linear or piecewise linear warping functions.
