Based on tslearn.barycenters that offers Soft-DTW barycenter computation It also provides a way to compute the silhouette coefficient for given clustering and metric A shapelets module includes an efficient implementation of the Learning Time-Series method from Grabocka et al. Warning: to use the sh...
然而,当涉及到时间序列聚类时,这是一个具有挑战性的问题,kmeans需要确定簇的数量这一点比较烦人,但是与层次聚类相比,k-Means和k-Medoids的聚类速度非常快,这使得它们非常适合于时间序列聚类,并在许多工作中被使用。k-Means和k-Medoids算法以“hard”或“soft”的方式构建聚类,这意味着一个对象要么是一个聚类的成...
Authors would like to thank Mathieu Blondel for providing code forKernel k-meansandSoft-DTW, and to Mehran Maghoumi for historch-compatible implementation of SoftDTW.
