| 摘 要： | 为解决高多元时间序列聚类算法的问题,采用了一种基于主元分析方法的多元时间序列聚类分析方法,利用MTS序列的前z个主元与每个簇的代表元素之间的Eros距离,将原有的复杂数据降维.在此基础上通过改进K-means算法对选取的多元时间序列的主元进行聚类分析,最后得到K个MTS聚类.理论分析和实验结果表明该算法能有效解决聚类问题.

| Abstract: | In order to solve the problem of Multivariate Time Series clustering algorithm,an efficient clustering algorithm for Multivariate Time Series-PCA-CLUSTER is proposed.Based on Eros distance between residual MTS data and cluster representing elements,the original MTS data dimension is reduced.Subsequently,K-neighbor clustering analysis was carried out on the principal component series of MTS,and finally K MTS cluster are obtained.The experimental results show that Theoretical analysis and the algorithm is effective for solving the clustering problem. |
