模糊聚类分析及其地质应用实例

摘要聚类分析直接利用相似矩阵或相关矩阵来分类,但它们本身存在矛盾,分类时也会出现矛盾。为消除这个矛盾,可采用模糊聚类分析。它的特点是,通过相似矩阵连续自乘,改造成模糊分类矩阵,随后按不同要求进行分类。本文旨在介绍模糊聚类分析的步骤和方法,并提供一个PC—1500袖珍机模糊聚类分析源程序。附两个算例。

FUZZY CLUSTER ANALYSIS WITH CASE STUDIES ON ITS GEOLOGIC APPLICATION

In the cluster analysis, the correlation matrix or the similarity matrix is directly used to make classification, but there is contradiction in itself, and paradox also occurs in the classification. In order to solve these problems, fuzzy cluster analysis can be adopted, in which the similarity Matrix is trans-formed into fuzzy classification matrix through continuous involution, and consequently classification is made according to different requirements. This paper introduces the methodology and the procedure of fuzzy cluster analysis, and provides a source program of fuzzy cluster analysis for PC-1500 pocket computer. Two examples are added in the paper.
