摘要 将经典的模糊C-均值聚类中的欧氏距离推广到广义欧氏距离,得到了加权模糊C-均值聚类的迭代公式,实证分析表明加权模糊C-均值聚类的结果与主成分分析的排序基本一致,特别适用于大样本的聚类与排序。 In this paper we extend classical Cluster Fuzzy C-Mean to weigh on Cluster Fuzzy C-Mean, gained iterative formula Powered on Cluster Fuzzy C-Mean. Demonstratively analyses indicate that result using this method is in accord with using Principal Components Analysis, it is especially helpful when dealing with large samples.
