摘要
决策形式背景的属性约简及其规则获取是形式概念分析领域的研究热点问题.基于决策形式背景的决策规则,研究了决策形式背景的属性约简问题.给出了决策形式背景的冗余规则的等价表示,以及决策形式背景的规则协调集的充分必要条件,定义了决策形式背景的辨识矩阵和辨识函数,给出了决策形式背景基于决策规则的属性约简方法,并举例说明了结果.
Attribute reduction and rule acquisition in decision formal context is a hot topic in formal concept analysis.The problem of attribute reduction in decision formal context is studied based on decision rules.Firstly,the equivalent representation of redundant rules and the necessary and sufficient conditions of rule coordination sets are given.Then the identification matrix and function of the decision formal context are defined.Finally,a method of attribute reduction based on decision rules in decision formal context is given,and the result is illustrated by an example.
