地质分类中一种新的模糊聚类方法

没有分类,就没有鉴别,也就无法认识客观事物.因此,分类是各个领域中经常遇到的基本问题之一.以定量分类为特征的聚类分析法,和一般的定性分析方法相比,失误的可能性小得多.因此,在分类问题上,该方法已经起了很大作用.但是,和其它任何方法一样,聚类分析法也有局限性.1.聚类分析法是建立在普通集合论基础之上的.任一集合A的特征函数C_Λ(X)只能用二值变量来描述.即:

A NEW METHOD OF FUZZY CLUSTERING IN THE GEOLOGICAL CLASSIFICATION

The prolongation and complexity of geological processes have resulted in many metallogenic stages. As data collected from geologic bodies are mostly products of polygenetic and superimposed processes, so the geologic marks or sample classification thus become obscure and complicated and sarisfactory results could not be obtained using the normal cluster analysis and fuzzy clustering for classification. On the basis of the fuzzy sets theory, a new method in fuzzy clustering is presented in this paper, whida can fully collect genetic information and make sieve analysis and classification correctly for the geological products.Effective results in study of metallogenic processes of gold deposits in Jiaodong area have been achieved.
