Abstract
AbstractSubsystem 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.KeywordsTopological SpaceBinary RelationApproximation OperatorClosure OperatorApproximation SpaceThese keywords were added by machine and not by the authors. This process is experimental and the keywords may be updated as the learning algorithm improves.
