The idea behind such a notion is to consider subsets of objects that characterize the different classes given by a decision system. Besides the formal definition of representative set of objects of a decision class, we present different mathematical properties of such sets and a relationship with classification tasks based on rough sets. © 2020, Springer Nature Switzerland AG.}, publisher = {Springer}, keywords = {Attribute reduction}, keywords = {Decision systems}, keywords = {Object reduction reduct}, keywords = {Rough Set Theory}, title = {Representative Set of Objects in Rough Sets Based on Galois Connections}, doi = {10.1007/978-3-030-52705-1_26}, author = {Madrid Labrador, Nicolás Miguel and Ramírez Poussa, Eloísa}, }
