摘要
介绍了模糊聚类的基本原理,指出了模糊聚类方法的具体步骤.采用极大极小法构成相似矩阵,运用传递闭包确定分类阈,通过分析统计量来确定最佳分类数目.以L-HL32普通液压油为例,对10个样品液压油的质量进行了分类.
The basic principle of fuzzy clustering is introduced,and the concrete steps of the fuzzy clustering method are pointed out.The similarity matrix is formed by the minimax method,and the classification threshold is determined by the transfer closure.The optimal number of classifications is determined by the analysis of statistics.Taking L-HL32 ordinary hydraulic oil as an example,the quality of the hydraulic oil of 10 samples was classified.
