WebOct 1, 2007 · Abstract. Dynamic Time Warping (DTW) has a quadratic time and space complexity that limits its use to small time series. In this paper we introduce FastDTW, an approximation of DTW that has a linear time and space complexity. FastDTW uses a multilevel approach that recursively projects a solution from a coarser resolution and … 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. However, the
