简单介绍了Rough理论厦相关概念,分析了A.Skowrond的分明矩阵法以厦改进方法。提出了一种基于布尔矩阵的属性约简方法,本方法用布尔矩阵来保存由信息系统直接生成的邻域分明仝合取范式,减少了存储空间.提高了计算效率。
This article simply introduced the Rough theory and relevant concepts,then analyzed the discernible matrix method by A.Skowrond and it's improving.We proposed a method of data reduction based on boolean matrix,this method use boolean matrix to save the neighbor valued discernible Conjunction normal form produced directly by the information system,this method can reduce the memory space,and improve computational efficiency.
