    Optimistic Decision-Theoretic Rough Sets in Multi-covering Space

    This paper discusses optimistic multigranulation decision-theoretic rough sets in multi-covering space. First, by using the strategy “seeking commonality while preserving difference”, we propose the notion of ...

    Covering-Based Optimistic Multigranulation Decision-Theoretic Rough Sets Based on Maximal Descriptors

    This paper investigates decision-theoretic rough set approach in the frameworks of multi-covering approximation space. We mainly discuss optimistic multigranulation decision-theoretic rough sets by employing m...
