Uncertainty Measurements of Inteval-Valued Intuitionistic Fuzzy Rough Sets
摘要
Abstract
The uncertainty measurement method of approximate set was used in the interval-valued intuitionis-tic fuzzy information system by using fuzzy entropy, the uncertainty measuring formula of the interval-valued intuitionistic fuzzy approximate operators was given. The definition of fuzzy rough membership function was generalized to rough membership function of interval-valued intuitionistic fuzzy sets through defining a new in-terval-valued intuitionistic fuzzy upper and lower approximate operators in the interval-valued intuitionistic fuzzy approximate space. Then, the entropy of interval-valued intuitionistic fuzzy rough set was defined by using fuzzy entropy of the interval-valued intuitionistic fuzzy rough membership functions, and the problem of uncertainty measurement on interval-valued intuitionistic fuzzy rough set was solved, some related properties of measure was discussed, so as to prove the rationality of the definition.关键词
