摘要
对工程上常用的最大树法和模糊C-均值算法的聚类结果进行比较,从算法本身角度分析了其聚类结果的相似和不同之处。通过仿真验证:最大树法比较适合于低维的小样本集;模糊C-均值算法不仅适合于低维的小样本集,而且也适用于团状的、每类样本数相差不大的、类与类间有交叠的高维大样本集,更便于计算机上编程实现。
Clustering results of fuzzy c-means algorithm and maximal tree method in common use of project are compared, similitude and difference of their clustering results are analyzed from algorithms' own angle. It is testified through simulation that maximal tree method is comparatively capable of small sample sets; and fuzzy c-means algorithms is not only capable of small sample sets, but also capable of multidimensional large sample sets of corps shape and discrepancy not too in sample number of every class and overlapping data among classes, still convenient for computer program realizing.
