摘要
对传统的区分矩阵法进行分析,提出一种基于等价类的约简算法。该算法的主要思想是将不相容决策表通过等价类划分转化为相容决策表,然后利用已有的区分矩阵方法对其约简。
For the inconsistent decision tables,this paper analyzes the traditional discernibility matrix method,and makes a new reduction algorithm on the basis of equivalent class.The algorithm＇s idea is to convert a inconsistent decision tables into a consistent decision table based on equivalent classes,then we can use the discernibility matrix calculate reduct and core.
