| 摘 要： | 粗糙集理论作为一种新型的软计算方法,在数据挖掘方面的应用越来越被人们所重视。利用粗糙集理论进行数据挖掘,得到知识规则,最重要的一点就是基于粗糙集的属性约简。文中在区分矩阵的基础上,改进了计算信息系统属性约简的方法,使属性约简计算量大幅度减小,可以快速得到给定要求下的属性约简。

| Abstract: | Rough set is a new method of soft calculation.It is being recognized gradually to use in date mining.Utilizing rough set executes data mining and obtains knowledge,attribution reduction is very important.In this paper,an improved reduction method of attribution for information system is proposed.It is based on discernable matrix.It largely makes reduction simply and convenient,and can obtain the attribution reduction fastly. |
