Subsystem Based Generalizations of Rough Set Approximations

Download www2.cs.uregina.ca

Abstract. Subsystem based generalizations of rough set approximations are investigated. Instead of using an equivalence relation, an arbitrary binary relation is used to construct a subsystem. By exploring the relationships between subsystems and diﬀerent types of binary relations, we examine various classes of generalized approximation operators. The structures of subsystems and the properties of approximation operators are analyzed.
