Topological and algebraic characterization of coverings sets obtained in rough sets discretization and attribute reduction algorithms

Abstract. A systematic study on approximation operators in covering based rough sets and some relations with relation based rough sets are presented. Two different frameworks of approximation operators in covering based rough sets were unified in a general framework of dual pairs. This work establis...
