【时间序列聚类】KMedoids聚类+DTW算法前⾔KMedoids的聚类有时⽐KMeans的聚类效果要好。⼿上正好有⼀批时序数据,今天⽤KMedoids试下聚类效果安装KMedoids可以使⽤sklearn的拓展聚类模块scikit-learn-extra,模块需要保证Python (>=3.6)scikit-learn(>=0.22)安装 scikit-learn-extraPyPi: pip install scikit-...
In order to solve the cold start problem, we proposed new algorithm based on the DTW Barycenter Averaging (DBA) algorithm. The results showed that our predicted values are very close to real values and achieve only 0.35 of the normalized mean absolute error rate, on average, for the WSDream...
