step_pattern定义了点之间的匹配模式,有好几种,具体查看官网(StepPattern — The dtw-python package 1.3.0 documentation (dynamictimewarping.github.io))。 window_type表示全局条件约束,也有几种模式,同查看官网(dtw — The dtw-python package 1.3.0 documentation (dynamictimewarping.github.io))。"none", ...
Welcome to the dtw-python package Comprehensive implementation ofDynamic Time Warping algorithms. DTW is a family of algorithms which compute the local stretch or compression to apply to the time axes of two timeseries in order to optimally map one (query) onto the other (reference). DTW output...
我在研究动态时间扭曲的时间序列。我需要绘制两个序列的数据点之间的对齐情况:s=[s1,s2,s3,...,sy]我想要达到这样的目标:或者更好的是,就像这样(除了这两个序列及其对齐之外,什么也没有):我知道dtw空间的存在,尽管它似乎不包括绘制对齐的方法我对使用Python进行绘图相当陌生,所以在 浏览0提问于2015-07-23得票...

python: 我們先創造出三個相同長度的資料ts1, ts2, ts3,從圖裡我們可以很明顯地看出ts1和ts2比較相似,第一種方法先透過最簡單的euclidean distance計算相似度,跑出的結果卻是ts1與ts3比較相近,因為euclidean distance僅考慮同個時間點下的兩的序列直線距離,無法捕捉到趨勢上的相似程度。
