WebJan 3, 2024 · Sorted by: 4 DTW often uses a distance between symbols, e.g. a Manhattan distance ( d ( x, y) = x − y ). Whether symbols are samples or features, they might require amplitude (or at least) normalization. Should they? I wish I could answer such a question in all cases. However, you can find some hints in: Dynamic Time Warping and normalization Webfirst step takes linear time while the second step is a typical DTW, which takes quadratic time, the total time complexity is quadratic, indicating that shapeDTW has the same computational complexity as DTW. However, compared with DTW and its variants (derivative Dynamic Time Warping (dDTW) [19] and weighted Dynamic Time …
