A new algorithm of computing the attribute is put forward based on the property of consistent information system that the probability distribution of condition attribution partitions relative to decision attribution partitions is one-point distribute.
属性核的确定对于求属性约简具有重要的意义,利用协调信息系统中条件属性的划分相对于决策属性划分的概率分布为单点分布的性质,提出一种新的求核算法。
Then bases on the relative probability distribution of consistent decision table are satisfied one-point distribute to judge whether the attribute is redundant attribute,and thus obtains reduction.
首先判断决策表是否为一致决策表;如果是不一致决策表,则通过最大相对概率分布将其转换为一致决策表;然后基于一致决策表的相对概率分布满足单点分布的性质来快速确定属性是否为冗余属性,从而求出约简;并通过MATLAB和UCI学习数据库验证了该算法的有效性和高效性。
