A novel similarity measure for pseudo-generalized fuzzy rough sets.

Various fuzzy generalizations of rough approximations have been made over the years. In this paper, the pseudo-generalized fuzzy rough sets are presented and some properties of the pseudo fuzzy rough approximation operators are investigated. It is necessary to measure the similarity between two pseudo-generalized fuzzy rough sets in some practical cases, such as pattern recognition, image processing and fuzzy reasoning. A novel similarity measure between two pseudo-generalized fuzzy rough sets is proposed in this paper. At the same time, we show that the similarity measure between two pseudo-generalized fuzzy rough sets can be given according to the pseudo-operation. [ABSTRACT FROM AUTHOR]
