| 摘 要： | 对Rough Set理论中的规则提取问题进行了研究，以利于信息不完备决策问题的解决．算法假定给定一个重要性阈值的前提下，将属性重要性进行比较．如果比此阈值小的属性则可省略，根据约简表则可得到相应的决策规则．文章还给出了一个计算实例说明了算法的计算过程．

| Abstract: | This paper introduces the research about the attain of rule on rough set theory to deal with un information. The algorithm compared with the necessary of attribute in the hypothesis of given necessary value, if the value of attribute is little than the value, these attribute can be default. So we can obtain the decision rule by the reduce table. In addition, this paper gives an example to show the process of the algorithm. |
