WebJul 31, 2024 · DTW Barycentric Averaging (DBA) is a method of averaging multiple discrete time series by finding the center of time aligned elements. It does this through an iterative process of adding sample patterns that are time aligned by DTW to a cumulative centroid pattern. WebRecently, a method of averaging called DTW Barycenter Averaging (DBA) was developed that is consistent with dynamic time warping. This method produces results suitable for classification and clustering of time series data, and is based on minimizing the within group sum of squares (WGSS) of the data. Because dynamic time warping is time scale ...
