| 摘 要： | 粗糙集属性约简就是在保持信息系统的分类和决策能力不变的条件下,删除不相关或不重要的属性,使原有系统得到简化。利用一种基于粗糙集的属性约简算法,通过计算属性在可分辨矩阵中出现的频率来定义属性的重要性,可使约简结果保持近似精度。实验表明该算法可以简化评教指标体系,降低信息系统所需存储空间。

| Abstract: | Attribute reduction of rough set is to remove irrelevant or unimportant attributes so as to simplify the system on the condition of the classification of information systems and the ability of decision-making remaining unchanged.An algorithm of attribute reduction based on rough set is proposed.This algorithm can make the reduction result keep the approximation by the way of calculating the importance of attributes based on the frequency of attributes appearing in the distinguish matrix.The experiment's res... |
