基于粒关系包含度矩阵的属性约简
Attribute reduction based on inclusiondegree matrix of the granular-relations
摘要
Abstract
Aiming at the problem of attribute reduction of decision information system,according to the simple and intuitive operations between granular matrices,a new concept about inclusion-degree matrix of the granular-relations is proposed.Then an attribute reduction algorithm about the compatible decision information system is designed according to those informations which are hidden in the inclusion degree matrix of the granular-relations.Finally,an example is given to illustrate the effectiveness of the designed algrithm.关键词
