摘要
本文对信息系统的属性集划分对象空间的能力进行研究,得出了一些有用的结果.根据这些结果,提出了一种新的约简方法.与现有的约简方法相比,本文方法无须构造区分矩阵,这不仅减少了计算工作量,还节省了大量的存储资源.举例验证了该约简方法的有效性.
The ability of attribute set of an information system to divide object sky be studied, and some useful results are obtained. Based on these results, an new reduction method is proposed by this paper. To compare with present methods, themethod of this paper not have to construct the distinguish matrix, so that not only the computation is reduced,but also the resources of memory is saved greatly. The effectiveness of this method is illustrated.
