WebMay 15, 2024 · The basis of DTW is found on the computations of distance /confusion matrix between two-time series. It can be shown in the below figure (a). In figure (a), values of time series A has been plotted in the x axis and values of time series B has been plotted in the y axis. The best alignment is shown by the green lines in (b). WebIn the context of shape-based time-series clustering, it is common to utilize the Dynamic Time Warping (DTW) distance as dissimilarity measure (Aghabozorgi et al.,2015). The calculation of the DTW distance involves a dynamic programming algorithm that tries to find the optimum warping path between two series under certain constraints.
