Abstract:Traditional rough set theory is mainly used to reduce attributes and extract rules in databases in which attributes are characterised by partitions, which the covering rough set theory, a generalisation of traditional rough set theory, covers.

First, we define different covering decision systems and their attributes’ reductions. Further, we describe the necessity and s… Show more
