WebCompute Dynamic Time Warping (DTW) similarity measure between (possibly multidimensional) time series and return it. DTW is computed as the Euclidean distance between aligned time series, i.e., if π is the optimal alignment path: D T W ( X, Y) = ∑ ( i, j) ∈ π ‖ X i − Y j ‖ 2. Note that this formula is still valid for the ... WebDynamic Time Warping. ¶.
