Firstly,the classification of probability rule is analyzed on the base of classic rough set concepts and extended to the equal relation of set in the indefinite system,namely,the upper and lower approximation space of research set is expressed in the form of conditional probability;then,according to the measure of probability rule,the attributes reductio.
首先在经典粗糙集概念的基础上分析概率规则的分类,并将其推广到不确定系统的集合等价关系中,即用条件概率的形式表示研究集合的上下近似空间;然后根据概率规则的测度从条件概率的角度利用条件属性的逼近精度的相关参数进行属性集的约简进而提取分类规则;最后给出了相关的仿真实验结果,结果表明带有概率测度的分类规则更合理。
