Data Mining Based on Rough Set

Pang Qianchao~1,Wang Yanmin~2 (1.College of Computer Zhejiang University,Hangzhou Zhejiang 310000;2.Dept.of Surveying and Mapping Engineering,Beijing 100044)  
The rough set theory is a new mathematical approach to data analysis based on classification of objects into similarity classes which are indiscernible with respect to some features.In this paper,basic theory of rough set is introduced using an examples,and the implementation of rule mining by variable precision rough set model based on reduction of decision-form feature is illustrated using an example.It is effective for rule mining based on rough set by the example.
