The algebraic structures of generalized rough set theory
Guilong Liu,William Zhu +1 more
TL;DR: The structures of the lower and upper approximations based on arbitrary binary relations in the generalized rough sets are presented and an algorithm to compute atoms for these two Boolean algebras is presented.
Journal ArticleDOI
Attribute selection with fuzzy decision reducts
TL;DR: This paper introduces the concept of fuzzy decision reducts, dependent on an increasing attribute subset measure, and presents a generalization of the classical rough set framework for data-based attribute selection and reduction using fuzzy tolerance relations.
Journal ArticleDOI
Theory and applications of granular labelled partitions in multi-scale decision tables
Wei-Zhi Wu,Yee Leung +1 more
TL;DR: A formal approach to granular computing with multi-scale data measured at different levels of granulations is proposed in this paper and the unravelling of decision rules at different scales in multi- scale decision tables is discussed.
Journal ArticleDOI
Combination of feature selection approaches with SVM in credit scoring
F. L. Chen,Feng-Chia Li +1 more
TL;DR: This study suggests that hybrid credit scoring approach is mostly robust and effective in finding optimal subsets and is a promising method to the fields of data mining.
Journal ArticleDOI
Attribute reduction based on evidence theory in incomplete decision systems
TL;DR: This paper deals with attribute reduction in incomplete information systems and incomplete decision systems based on Dempster-Shafer theory of evidence and shows that in an incomplete information system an attribute set is a belief reduct if and only if it is a classical reduct and a plausibility consistent set must be a classical consistent set.

A reduction algorithm meeting users' requirements
TL;DR: An approach to dealing with how to find a particular reduct including those attributes anterior in the attribute order is proposed and its completeness for reduct is proved.
Book ChapterDOI
Logical Analysis of Indiscernibility
Stéphane Demri,Ewa Orłowska +1 more
TL;DR: The role of indiscernibility in the analysis of vagueness of concepts and in concept learning is explained and deduction methods that enable us making inferences from incomplete information in the presence of indiscERNibility are developed.
Proceedings Article
Reducts and Constructs in Attribute Reduction
TL;DR: The topological aspects of such reducts are focused on, identifying some of their limitations and introducing alternative definitions that do not suffer from these limitations.
Book ChapterDOI
Conflicts and negotations
TL;DR: This paper shows how the conflict situation and development can be represented and studied by means of conflict graphs and an illustration of the introduced concepts by the Middle East conflict is presented.
