Generalizations of rough set concepts
A.S. Salama, M. E. Abd El-Monsef · Journal of King Saud University - Science · 2010
In this paper, we generalized the notions of rough set concepts using two topological structures generated by general binary relation defined on the universe of discourse. New types of topological rough sets are initiated and studied using new types of topological sets. Some properties of topological rough approximations are studied by many propositions.
