The two-universes multi-granularity fuzzy rough set model is an effective tool for handling uncertainty problems between two domains with the help of binary ...

Abstract. In this paper we focus upon a comparison of some generalized rough approximations of sets, where the classical indiscernibility relation is ...

In this paper we generalize the rough set model over dual-universes in fuzzy approximation space to intuitionistic fuzzy case. Concretely, based on the cut ...

In [27], four types of rough fuzzy approximation operators on two universes have been proposed. Zhang et al. [36] studied the gener- alized interval-valued ...

Abstract. This paper focuses on rough approximation operators in group mapping. The relation- ships between rough set theory and group theory are considered ...

The basic structure of rough set is an approximation space consisting of a universe of discourse and a binary relation imposed on it. In classical approximation ...
