Abstract:
Against the measuring problem of similarity between simulation time-series data and reference time-series data with different lengths or distorted timeline, a similarity measuring method based on DTW is proposed. Considering the trends of time-series data, a new windowing algorithm for Dynamic Time Warping (DTW) is presented. The correctness of the algorithm is proved. On this basis, simulation time-series data and reference time-series data are segmented according to event information, and the overall similarity between them is obtained by calculating DTW distance in different segments. Finally, an example is given to validate the reasonability and validity of the proposed method.
