基于加权特性关系的扩展粗糙集模型
Extended rough set model based on weighted characteristic relation
摘要
Abstract
Considering data missing in the incomplete information system and the importance of the attributes, the weighted characteristic relation is proposed. Then, an extended rough set model under the weighted characteristic relation and the definitions of its lower and upper approximations and their properties are given. Finally an example is used to illustrate the method of calculating approximations in this extended rough set model.关键词
