WebCompute Dynamic Time Warp and find optimal alignment between two time series. Details 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. WebMay 20, 2016 · In R the dtw package does include multidimensional DTW but I have to implement it in Python. The R-Python bridging package namely "rpy2" can probably of help here but I have no experience in R. I have looked through available DTW packages in Python like mlpy, dtw but are not help.
