WebLevenstein distance and dynamic time warp. I am not sure how to draw parallel between the Wagner–Fischer algorithm and dtw algo. In both case we want to find the distance of each index combination (i,j). In Wagner–Fischer, we initiate the distance by the number of insert we'd have to do from one empty string to another. Time Warp Edit Distance (TWED) is a measure of similarity (or dissimilarity) for discrete time series matching with time 'elasticity'. In comparison to other distance measures, (e.g. DTW (dynamic time warping) or LCS (longest common subsequence problem)), TWED is a metric. Its computational time complexity is , but can be drastically reduced in some specific situations by using a corridor to reduce the search space. Its memory space complexity can be reduced to . It was first proposed i…
