Tracking Recurring Patterns in Time Series Using Dynamic Time Warping
Rik van der Vlist, Cees Taal, Richard R. Heusdens · 2019
Dynamic time warping (DTW) is a distance measure to compare time series that exhibit similar patterns. In this paper, we will show how the warping path of the DTW algorithm can be interpreted, and a framework is proposed to extend the DTW algorithm. Using this framework, we will show how the dynamic programming structure of the DTW algorithm can be used to track repeating patterns in time series.
