- Abstract:
-
The rough set theory is a new mathematical tool to study vague and unc ertain information, and is widely used in intelligent systems. In this paper, th e basic ideas of rough set theory are introduced,and the notion of up and low approximation sets, attribute reduction, core and some extensions of rough set t heory are also presented. Then the application of rough set theory in intelligen t systems is explored, mainly including data preprocessing method by using attri bute reduction based on rough set theory, analysis of correlations between attri butes and system, modeling and control. Finally, the difficulties and possible f ields for the application of rough set theory are discussed.
