The algebraic structures of generalized rough set theory

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.

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.

Theory and applications of granular labelled partitions in multi-scale decision tables

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.

Combination of feature selection approaches with SVM in credit scoring

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.

Data mining tasks and methods: Rule discovery: rough set approaches for discovering rules and attribute dependencies

TL;DR: This article presents an elementary overview of techniques for data analysis and predictive modeling from data using the rough set approach, focused on the application of the basic rough set model to knowledge discovery.

Rough Set Methods and Applications

TL;DR: The rough set method was employed to discover ill-defined relations underlying the implemented perceptual model of hearing, which can be used for suppressing the noise affecting transmitted audio signals.

Tree-Like Parallelization of Reduct and Construct Computation

TL;DR: The paper presents a so-called constrained tree-like model of parallelization of this task and illustrates practical behaviour of this algorithm in a computational experiment.
