Attribute Reduction and Information Granularity [PDF]

open access: yesJournal 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 ...

Ensemble-Based Neighborhood Attribute Reduction: A Multigranularity View [PDF]

open access: yesComplexity, 2019
Recently, multigranularity has been an interesting topic, since different levels of granularity can provide different information from the viewpoint of Granular Computing (GrC). However, established researches have focused less on investigating attribute

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.

An Attempt of Object Reduction in Rough Set Theory [PDF]

open access: yes, 2019
Attribute reduction is a popular topic in rough set theory; however, object reduction is not considered popularly. In this paper, from a viewpoint of computing all relative reducts, we introduce a concept of object reduction that reduces the number of ...
