聚类分析在地质工作中已经得到广泛的应用。但其计算相当复杂,一般要由电子计算机完成。此外,因相关系数或相似系数矩阵中各元素并不一定具有集合论中分类的充要条件所需的传递性,故应用多元统计选取最大值的分类方法就可能得不到满意的结果。地质工作中的分类问题一般都是模糊的。因而利用模糊数学的运算方法解决地质工作中的分类问题,会比常规的聚类方法更合理和简便。本文简略介绍模糊聚类方法的原理及其应用。
Cluster analysis has been widely used in geological work. However, its calculation is rather complicated and generally needs to be done by an electronic computer. In addition, because the elements of the correlation coefficient or similarity coefficient matrix do not necessarily have the necessary and sufficient conditions for the classification in set theory, the classification method using the maximum value of the multivariate statistics may not be satisfactory. Geological classification of the work are generally vague. Therefore, using fuzzy mathematics to solve the classification problem in geological work will be more reasonable and convenient than the conventional clustering method. This article briefly introduces the principle of fuzzy clustering method and its application.
