As a result, efforts WebThe DTW distance is defined as the element DTW[n,m], thus the top right element of the accumulated distance matrix and it is the sum of the cost along the best possible warping path. Now you can use backtracking to identify the best possible warping path by iteratively choosing the minimum neighbour starting from the top right. check engine light not going off
