一种基于粗糙集理论的数据挖掘算法的研究

Research on A Data Mining Algorithm Based on Rough Set

研究了粗糙集理论在数据挖掘中的应用,提出了一种基于粗糙集理论的数据挖掘算法.首先对信息系统的数据加工泛化,构造其二进制可辨矩阵.对矩阵进行化简得到属性约简并生成规则.最后,结合银行申请信用卡的实例,利用上述方法进行数据挖掘,消去冗余属性,抽取决策规则.

The paper studies the application of rough set theory in data mining, presents a data mining approach based on rough set theory. Firstly, it deals with the data of information system and create the binary discernible matrix. The attribute reduction and rules are gained. With this method, the paper eliminates the redundant attributes and get decision-making rules in the application for bank creditcards at last.
