Journal ArticleDOI
Approaches to knowledge reduction based on variable precision rough set model
TL;DR: It is proved that for some special thresholds, β lower distribution reduct is equivalent to the maximum distribution reduction reduct, whereas β upper distribution reduCT is equivalents to the possible reduct.
Journal ArticleDOI
Granular Computing and Knowledge Reduction in Formal Contexts
Wei-Zhi Wu,Yee Leung,Ju-Sheng Mi +2 more
TL;DR: Granular structure of concept lattices with application in knowledge reduction in formal concept analysis is examined in this paper and knowledge hidden in such a context is unraveled in the form of compact implication rules.
Journal ArticleDOI
On characterizations of ( I,T)-fuzzy rough approximation operators
Wei-Zhi Wu,Yee Leung,Ju-Sheng Mi +2 more
TL;DR: A general framework for the study of (I,T)-fuzzy rough approximation operators within which both constructive and axiomatic approaches are used, and an operator-oriented characterization of rough sets is proposed.
Journal ArticleDOI
Knowledge reduction in random information systems via Dempster-Shafer theory of evidence
TL;DR: It is proved that both of belief reduct and plausibility reduct are equivalent to classical reduct in (random) information systems.
Journal ArticleDOI
A rough set approach for the discovery of classification rules in interval-valued information systems
TL;DR: In this article, a rough set approach is proposed to discover classification rules through a process of knowledge induction which selects decision rules with a minimal set of features for classification of real-valued data.
