基于数据场的类簇中心选取及其聚类
Clustering center selection and clustering based on data field
摘要
Abstract
In view of the existing clustering algorithms with widespread low clustering quality, parameter dependency and outlier effects obvious,in this paper,a clustering method based on the field data is proposed.The algorithm has its basis in the assumptions that cluster centers are surrounded by neighbors with lower local potential and that they are at a relatively large distance from any points with a higher local potential.According to the characteristics that the potential value of isolated point is equal to zero,remove the outlier and finally the other object points are divided into larger than its potential value and nearest neighbor type of clusters, so as to achieve clustering. Simulation results show that the pro-posed algorithm is effective and has no effect on the shape of the data set,and it can find out clusters center and outliers accurately without artificial parameters.关键词
