Dynamic time warping (DTW)- Searching the best alignment Multiscale DTW or fastDTW speeds up the dynamic time warping algorithm by running DTW on a reduced representation of the data.
FastDTW algorithm is linear in both time and space complexity, and it avoids the brute-force dynamic programming approach of the standard DTW algorithm by using a multilevel approach. The time series are initially sampled down to a very low resolution.

DTW between multiple Time series ¶ To compute the DTW distance measures between all sequences in a list of sequences, use the method dtw.distance_matrix. You can speed up the computation by using the dtw.distance_matrix_fast method that tries to run all algorithms in C. Also parallelization can be activated using the parallel argument.

Python implementation of FastDTW, whis is an approximate Dynamic Time Warping (DTW) algorithm that provides optimal or near-optimal alignments with an O(N) time and memory complexity.
well, fastdtw is an approximation, as it says in the link that you provided. Therefore it is to be expected, that the mapping is different. – Nikolas Rieble Jul 26 '16 at 8:59 dynamic time warping; fast DTW; dynamic warping window; DWW; data mining; kNN classification; k-nearest neighbour; time series; FastDTW; upper bounds; pattern recognition.

For larger time series (containing 3000 samples in my case) the situation looks a bit different: * dtw.distance(x,y): 21.120484339067534 * dtw.distance_fast(x,y): 0.35772456875758607 * fastdtw(x,y): 1.0159217517881522 * pydtw.dtw(x,y): 0.06623724053156366 – Hagbard Sep 24 '18 at 11:44 Calculate each MFCC to compare wave file A and wave file B, and then use FastDTW to measure the distance after two sets of MFCCs. We compared the four wave files and obtained the Euclidean distance value. The values below are the Euclidean distance values. 675.0095954620155 A.wav vs. A2.wav. 998.7554375714773 A.wav vs B.wav

Aug 02, 2018 · WASHINGTON – William Beaumont Hospital, a regional hospital system based in the Detroit, Michigan area, will pay $84.5 million to resolve allegations under the False Claims Act of improper relationships with eight referring physicians, resulting in the submission of false claims to the Medicare, Medicaid and TRICARE programs, the Justice Department announced today. In time series analysis, dynamic time warping (DTW) is an algorithm for measuring similarity between two temporal sequences which may vary in time or speed. For instance, similarities in walking patterns could be detected using DTW, even if one person was walking faster than the other...
