This code is supporting 3 research papers: 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 ... 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 ... push bath plug not working
