不相容决策表的核属性计算

A Calculation for Core Attributes of Inconsistent Decision Table

文章针对不相容决策表核属性的计算问题,提出了两种基于粗糙集代数观的核属性计算新方法,并分别与传统代数定义下以及信息熵定义下核属性计算方法进行比较,分析了各方法之间的异同、相互间的关系及各方法的不同适应范围。

The problem of calculating the core attributes of an inconsistent decision table is studied.And two algorithms for this problem are presented.The difference and relationship among these two algorithms and other two algorithms based on traditional algebra view and information view are also analyzed.
