Multigranulation Supertrust Model for Attribute Reduction [PDF]

open access: yesIEEE 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.
