Attribute Reduction and Information Granularity [PDF]
Journal of Systemics, Cybernetics and Informatics, 2003 In the view of granularity, this paper analyzes the influence of three attribute reducts on an information system, finding that the possible reduct and m - decision reduct will make the granule view coarser, while discernible reduct will not change the ...

Multigranulation Supertrust Model for Attribute Reduction [PDF]
IEEE Transactions on Fuzzy Systems, 2021 As big data often contains a significant amount of uncertain, unstructured, and imprecise data that are structurally complex and incomplete, traditional attribute reduction methods are less effective when applied to large-scale incomplete information systems to extract knowledge.
