模糊C-聚类分析：从随机初始化划分矩阵开始迭代-Fuzzy C-cluster analysis: start from the the random initialization divided matrix iteration

This paper presents a new cluster validity index for nding a suitable number of fuzzy clusters with crisp and fuzzy data. The new index, called the ECAS-index, contains exponential compactness and separation measures. These measures indicate ho
