Dynamic time warp python
WebDetails. The 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. The local distance between elements of x (query) and y (reference) can be ...
