一种基于相对信息粒度的属性约简算法
An Attribute Reduction Algorithm Based on Relative Information Granularity
摘要
Abstract
In order to find reduction in decision information system,on the basis of the existent reduction algorithm and granu?lar computing theory,this paper depicts knowledge by using information granular base from two aspects:semantic and grammar. Then,attribute sets＇granulating ability is measured by relative information granularity and this paper gives an attribute reduction al?gorithm based on relative information granularity. Finally,experimental results verify the effectiveness of this algorithm.关键词
