Study on representation of uncertainty rough information entropy in rough set

In the paper, the concept of rough information entropy is proposed. The monotony between the uncertainty of knowledge in the rough set theory and its corresponding rough entropy is proved. The rough entropy of the uncertainty of ordinary set and fuzzy set, and the monotonous relation between the unc...
