WebJan 26, 2024 · Dynamic time warping (DTW) is a distance-based algorithm that is used for measuring the distance between two time series. DTW does this by calculating the distances between each point in the time series and summing these for the overall distance. The algorithm is constructed to deal with slight shifts between very similar …
