粗糙集理论的主要思想是在保持信息系统分类能力不变的前提下,通过知识约简,导出问题的决策和分类规则:本文提出一种基于信息量的属性约简和规则提取的集成算法,并结合汽车里程试验数据进行验证,通过仿真实验,表明了该算法的有效性和可行性。
The main target of Rough Set theory is reducing the attribute and getting the effective rules based on keeping the classifiable ability of information system. According to the Rough Set theory,an integrated algorithm based on information quantity and value reduction is proposed, and then it is used to analysis car's data, obtaining the core and effective rules. For the same reason this algorithm can also be applied to others area.
