| 摘 要： | 主要对Rough Set理论中的属性约简问题进行了研究,从寻找属性约简的两个角度出发,利用文献5]中不可分辩类的定义及属性重要性的讨论,通过定义子集可辨识矩阵Ms(i,j)构造了一种广义核的启发式算法,并通过Delphi程序验证了该算法对实例和UCI数据库的有效性。

| Abstract: | This paper mainly discusses the attribute reduction in Rough Set theory.It begins with the methods of core set searching,then uses the results of references paper5],the undistributed class and the significance,meanwhile,gives the definition of discernibility sub-matrix which proposing a heuristic algorithm based on General core set for attribute reduction;finally,the experiment shows that it can get better effect and it also shows the reduction results of UCI database using this algorithm. |
