Rough sets for pattern classification using pairwise-comparison-based tables

Rough sets and decision tables

A New Approach for Knowledge Based Systems Reduction using Rough Sets Theory (RESEARCH NOTE)

Problem of knowledge analysis for decision support system is the most difficult task of information systems. This paper presents a new approach based on notions of mathematical theory of Rough Sets to solve this problem. Using these concepts a systematic approach has been developed to reduce the size of decision database and extract reduced rules set from vague and uncertain data. The method ha...

T-Rough Sets Based on the Lattices

The aim of this paper is to introduce and study set- valued homomorphism on lattices and T-rough lattice with respect to a sublattice. This paper deals with T-rough set approach on the lattice theory. The result of this study contributes to, T-rough fuzzy set and approximation theory and proved in several papers. Keywords: approximation space; lattice; prime ideal; rough ideal; T-rough set; set...

Decision Tables Aggregation in Rough Sets Approximation

The Dominance-based Rough Set Approach (DRSA) is an extension of Rough Sets Theory to handle multicriteria classification problems by authorizing preferenceordered attributes. The DRSA assumes the existence of a single decision table while real-world decision problems imply generally several experts with different decision tables. The objective of this paper is to propose an algorithm for the a...

The Amount of Meritocracy Establishment Using Rough Sets Theory

The amount of meritocracy system establishment in the government agencies of Ahvaz is assessed in this study. Meritocracy is a system in which the job benefits and situations are given to the people just on the basis of merit and not based on the gender, social class, ethnicity or wealth. Statistical society is the employers of government organizations of Ahvaz (N=10377) and the volume of sampl...
