Impact of Local Congruences in Attribute Reduction [PDF]
Information Processing and Management of Uncertainty in Knowledge-Based Systems, 2020 Local congruences are equivalence relations whose equivalence classes are convex sublattices of the original lattice. In this paper, we present a study that relates local congruences to attribute reduction in FCA. Specifically, we will analyze the impact in the context of the use of local congruences, when they are used for complementing an attribute ...

Incremental Attribute Reduction Method Based on Chi-Square Statistics and Information Entropy
IEEE Access, 2020 Attributes in datasets are usually not equally significant. Some attributes are unnecessary or redundant. Attribute reduction is an important research issue of rough set theory, which can find minimum subsets of attributes with the same classification ...

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.
