参考下面这个博客里面的文章,自己理解了又敲了一遍,加深理解,在此分享给大家。 https://nipunbatra.github.io/blog/2014/dtw.htmlhttps://en.wikipedia.org/wiki/Dynamic_time_warping
这样规整的跨度有点大了,就不再是微调时间序列中时间不对齐了,不符合实际呀。 所以又有了DTWwith Warping Window,现在规整跨度,效果如下所示。只需稍微改动动态规划的代码的循环范围。 参考资料:https://www.cnblogs.com/Daringoo/p/4095508.html https://en.wikipedia.org/wiki/Dynamic_time_warping...

如上图1所示,如果序列长短不一,或时间步不对齐的时候,欧氏距离是无法有效计算两个时间序列的距离,特别是在峰值的时候。 图2则是DTW算法,首先将其中一个序列进行线性放缩进行某种“扭曲”操作,以达到更好的对齐效果,可以存在一对多mapping的情况,适用于复杂时间序列,属于弹性度量 ...
Also, wikipedia is useful as it lists several available tools which hava already implemented the algorithm.在日常的生活中我们最经常使用的距离毫无疑问应该是欧式距离，但是对于一些特殊情况，欧氏距离存在着其很明显的缺陷，比如说时间序列，举个比较简单的例子，序列A：1,1,1,10,2,3，序列B：1,1,1,2,...
