摘要:

本文主要研究基于两类新的决策规则,即I-决策规则和II-决策规则的形式化决策上下文的规则获取和属性约简。这些规则的前提是面向对象的概念,结论分别是形式概念和面向属性的概念。给出了I-决策规则和II-决策规则的规则获取算法。这些算法与现有的算法进行了比较分析,这表明在这项研究中提出的算法表现良好。给出了利用相容性矩阵保持I-决策规则和II-决策规则的属性约简方法。

英文摘要:

This paper mainly studies the rule acquisition and attribute reduction for formal decision context based on two new kinds of decision rules, namely I-decision rules and II-decision rules. The premises of these rules are object-oriented concepts, and the conclusions are formal concept and property-oriented concept respectively. The rule acquisition algorithms for I-decision rules and II-decision rules are presented. Some comparative analysis of these algorithms with the existing algorithms are examined which shows that the algorithms presented in this study behave well. The attribute reduction approaches to preserve I-decision rules and II-decision rules are presented by using discernibility matrix.
