Attribute Reduction Based on Rough Approximation Set in Algebra and Information Views
IEEE Access, 2016 Rough set proposed by Pawlak in 1982 is an important tool to process uncertain information. As an extended model of rough set, an approximation set model of rough set was proposed and proved to be feasible to establish an approximation target set with ...

A New Algorithm for Attribute Reduction Based on Discernibility Matrix
, 2007 Attribute reduction is one of the key problems in the theoretical research of Rough Set, and many algorithms have been proposed and studied about it. These methods may be divided into two strategies (addition strategy and deletion strategy), which are based on adopting different heuristics or fitness functions for attribute selection. In this paper, we

Application of Rough Set Theory in Fault Diagnosis of Roller Bearing
Gong-kuang zidonghua, 2010 Rough set is a soft computing method which needn’t any validated knowledge and theoretics deducing,just depends on original data,and it aims at discovering latent laws and rules.Its core task is reducing data in order to get the simplest decision rules ...

Rough set model based on the labelled tree
Tongxin xuebao, 2010 In order to characterize and deal with the vagueness and uncertainty of structured data as well as the compositions and contents implied within semi-structured data models,a labelled tree rough set model（LTRS） was presented by extending the traditional ...
