Structure-Based Attribute Reduction in Variable Precision Rough Set Models
Masahiro Inuiguchi · Journal of Advanced Computational Intelligence and Intelligent Informatics · 2006
In this paper, structure-enhancing approaches to attribute reduction are proposed. Ten kinds of meaningful reducts are defined. The relations among them are clarified. Moreover their relations to reducts by structure-preserving approaches are also investigated. A few computational approaches to the proposed reducts are briefly described.
