Rough Set Theory

open access: yes, 2008
Rough set theory (RST), since its introduction in Pawlak (1982), continues to develop as an effective tool in classification problems and decision support. In the majority of applications using RST based methodologies, there is the construction of ‘if .. then ..’ decision rules that are used to describe the results from an analysis.

Rough sets theory

Chemometrics and Intelligent Laboratory Systems, 1999
Abstract The basic concepts of the rough set theory are introduced and adequately illustrated. An example of the rough set theory application to the QSAR classification problem is presented. Numerous earlier applications of rough set theory to the various scientific domains suggest that it also can be a useful tool for the analysis of inexact ...

Modal reasoning and rough set theory

open access: yes, 1998
In this paper, we would like to present some modal logics with semantics based on rough set theory and related notions. In addition to surveying some well-known results about the links between modal logics and rough set theory, we also develop some new applied logics inspired by generalized rough set theory.

Integrating rough set theory and medical applications

open access: yesApplied Mathematics Letters, 2008
Medical science is not an exact science in which processes can be easily analyzed and modeled. Rough set theory has proven well suited for accommodating such inexactness of the medical profession.

Contributions to the Theory of Rough Sets

Fundamenta Informaticae, 1999
We study properties of rough sets, that is, approximations to sets of records in a database or, more formally, to subsets of the universe of an information system. A rough set is a pair 〈L, U〉 such that L, U are definable in the information system and L ⊆ U.

Topology Theory on Rough Sets

IEEE Transactions on Systems, Man, and Cybernetics, Part B (Cybernetics), 2008
For further studying the theories and applications of rough sets (RS), this paper proposes a new theory on RS, which mainly includes topological space, topological properties, homeomorphism, and its properties on RS by some new definitions and theorems given.
