摘要
本文指出文献[2]中一个提取不相容决策表决策规则的分解处理方法存在的错误,并且分析错误产生的原因.在此基础上,本文进一步对这种分解方法进行考察,给出了原始不相容决策表和分解后的子决策表之间有关核属性和属性约简等方面的若干关系和性质.
We point out in this paper that there is an intrinsic error in a method proposed in the monograph [2]for extracting rules from an inconsistent decision table by some decomposition technique and analyze the reasons resulting in this error. Then. we study and scrutinize the relationship between core attributes and reduets of the original inconsistent decision table and that of its consistent sub tables after decomposition.
