摘要
数据挖掘是一门新兴技术。在数据提取中如何去除冗余数据是数据挖掘研究的重点之一。在研究粗糙集理论的基础上,将属性约简法应用到数据挖掘的知识约简中,可有效地删除冗余数据,并能取得较好的约简结果。
Data Mining is a new technology in this information time. How to rel ease redundant data in the procedure of data acquisition is one of important stu dy object in data mining. In this paper the method of attribute reduction is use d in knowledge reduction of data mining based on rough set. The result shows the method can delete the redundant data efficiently and achieve the better reducti on.
