摘要
Abstract
In order to overcome the weakness of K‐Means algorithm which is sensitive to outliers ,and to improve the quality of K‐Means clustering algorithm ,the paper makes an in -depth study on the traditional K‐Means algorithm and proposes an improved clustering algorithm based on the PAM algo‐rithm and the cluster threshold .T he proposed method first samples the clustering data and then em‐ploys the PAM algorithm to obtain the clustering center of the sample data as the initial center of K‐Means algorithm .By calculating the threshold for each cluster dynamically in the iterative process of clustering ,the outliers can be excluded from the dataset .Experimental results indicate that the pro‐posed algorithm have been shown lower computational cost and higher clustering accuracy .关键词
