  • Abstract
    Due to the phenomenon that the information can be lost in the process of data discretization of traditional rough set, the paper introduces the fuzzy set, and presents a two-step data preprocessing algorithm based on the grey correlative degree and fuzzy rough set. Firstly, this algorithm filters the attributes with the grey correlative degree. Secondly, the fuzzy distinguish matrix is used to reduce the rest attributes set. Finally, the algorithm is demonstrated effectively through the simulation experiment.
