模糊主成分模糊聚类的原理、模型及地质应用

THE PRINCIPLE AND MODELS OF FUZZY PRINCIPAL COMPONENT FUZZY CLUSTERING AND ITS APPLICATION IN GEOLOGY

模糊性、结构性与随机性一样,都是地球科学的基本属性。本文在评述Bezdek的FCE法的基础上,提出了模糊主成分模糊聚类法的原理和模型。所给出的椭球模式意义下参数的选择调整原则是建立在客观样本的子结构统计特征上的,因此减少了主观因素对聚类结果的影响。

Like the probability , the fuzziness and the structure are the essential attributes of geosciences .Commenting on the Bezdek's FCE,this paper proposes the principle and models of fuzzy principal component fuzzy clustering . In the meaning of the elliptotype of each cluster , some parameters which define the cluster patterns are chosen and adjusted according to the statistical characteristics of substructures in an objective sample . In this way , influnces on the result of clustering by subjective factors are reduced .
