WebDynamic Time Warping (DTW) 1 is a similarity measure between time series. Let us consider two time series x = ( x 0, …, x n − 1) and y = ( y 0, …, y m − 1) of respective lengths n and m . Here, all elements x i and y j are assumed to lie in the same d -dimensional space. In tslearn, such time series would be represented as arrays of ... shepard publications

WebDynamic Time Warping is a method for measuring similarity between two time series, which may vary in their speed. It can be used for pattern matching and anomaly detection. Fast DTW is a twisted version of DTW to accelerate the computation when the size of the time series is huge. It recursively reduces the size of the time series and calculate ...
