| 摘 要： | 介绍了粗糙集的概念和约简的相关定义,提出了基于粗糙依赖的属性约简算法.通过差别矩阵求核,并计算非核属性粗糙依赖值,从而确定相对属性约简.以远程教学网络课程等级评价为例进行算法验证,并通过基于值核的值约简算法提取决策规则,实践证明得到了满意的结果.

| Abstract: | This concept of rough sets and definitions of reduction were introduced.A reduction algorithm based on rough dependency was proposed.The core was gained by the discernable matrix,and rough dependency of non-core attribute was calculated in order to get the relative attribute reduction.It's verified through the example of remote education network course degree estimation.And the decision rules through value reduction based on value core were extracted.The result is satisfactory. |
