| Abstract: | 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. |

| Keywords: | Rough Set discernibility matrix data reduction boolean matrix |
