WebMar 29, 2024 · With respect to fastdtw, this is an approximate method. So the result will likely differ from the exact output. In most cases, however, standard DTW is faster than fastdtw because it is easier to optimize for a cpu (e.g. dtaidistance is >100x faster than fastdtw). See also the comparison by Wu and Keogh [3]. [1] Keogh, E. (2002).
