摘要: 文献[9]给出了一种决策表的代数约简快速属性约简算法,但有时得不到正确的结果,首先给出算例指出其不足,然后给出改进的属性重要性及其快速属性约简算法,它能保证得到正确的代数约简结果。数值算例也验证了其正确性。
关键词: 不一致决策表, 属性重要性, 属性约简, 核属性
Abstract: The attribute reduction algorithm suggested by literature[9] can not get correct results in some cases for decision table.Its defect is pointed out by a counterexample and then a modified attribute significance measuring method and quick reduction algorithm based on it are proposed.It ensures that we can obtain a correct algebra attribute reduction.Its validity is verified by some numerical examples.
Key words: inconsistent decision table, attribute significance, attribute reduction, core attribute
