Web1.2.2 Dynamic Time Warping is the Best Measure It has been suggested many times in the literature that the problem of time series data mining scalability is only due to DTW’s oft-touted lethargy, and that we could solve this problem by using some other distance measure. As we shall later show, this is not the case.
