Abstract

The theory of rough sets is a powerful tool for data analysis and knowledge discovery from imprecise and ambiguous data. A variable precision fuzzy rough set model based on fuzzy covering is proposed in this study. Some properties of rough approximation operators of the variable precision fuzzy rough set model based on fuzzy covering are discussed. It is a further and important generalization of rough set model.
