WebFeb 4, 2024 · The results for the same data and the same distance metric seems to differ between dtwand accelerated_dtwas well as the way the distance metric is specified. In the following example, I would expect that all three results are equal given that the data and distance metric are the same but that's clearly not the case. Is this expected? Web动态时间扭曲（DTW）是一种计算两信号间路径的方法，它能最小化两信号之间的距离。 这种方法最大的优势就是他能处理不同长度的信号。 最初它是为了进行语言分析而被发明出来，DTW 通过计算每一帧对于其他所有帧的欧几里得距离，计算出能匹配两个信号的最小距离。 一个缺点就是它无法处理缺失值，所以如果你的数据点有缺失，你需要提前插入数据 …
