In time series analysis, dynamic time warping (DTW) is an algorithm for measuring similarity between two temporal sequences, which may vary in speed. For instance, similarities in walking could be detected using DTW, even if one person was walking faster than the other, or if there were accelerations and … See more This example illustrates the implementation of the dynamic time warping algorithm when the two sequences s and t are strings of discrete symbols. For two symbols x and y, d(x, y) is a distance … See more The DTW algorithm produces a discrete matching between existing elements of one series to another. In other words, it does not allow time-scaling of segments within the … See more Averaging for dynamic time warping is the problem of finding an average sequence for a set of sequences. NLAAF is an exact method to average … See more Amerced Dynamic Time Warping (ADTW) is a variant of DTW designed to better control DTW's permissiveness in the alignments that it allows. The windows that classical DTW uses to constrain alignments introduce a step function. Any warping of the path … See more Fast techniques for computing DTW include Early Abandoned and Pruned DTW, PrunedDTW, SparseDTW, FastDTW, and the MultiscaleDTW. A common task, retrieval of similar time series, can be accelerated by using lower bounds such as … See more A nearest-neighbour classifier can achieve state-of-the-art performance when using dynamic time warping as a distance measure. See more In functional data analysis, time series are regarded as discretizations of smooth (differentiable) functions of time. By viewing the … See more Web时间序列分类方法：动态时间规整算法DTW和R语言实现. 拓端tecdat. 374 0. 10:12. Dynanmic Time Warping（DTW）. 爱上学习和生活. 2683 5. 07:00. How DTW (Dynamic Time Warping) algorithm works（有字幕）.
