Variable Neighborhood Search for Attribute Reduction in Rough Set Theory

Attribute reduction is a combinational optimization problem in data mining domain that aims to find a minimal subset from a large set of attributes. The typical high dimensionality of datasets precludes the use of greedy methods to find reducts because of its poor adaptability, and requires the use of stochastic methods. Variable Neighborhood Search (VNS) is a recent metaheuristic and have been...

Fuzzy-Rough set Approach to Attribute Reduction

Attribute Reduction has a significant role in different branches of artificial intelligence like machine learning, pattern recognition, data mining from databases etc. This paper deals with reduction of unimportant attribute(s) for classification and decision making, using Fuzzy-Rough set. A survey of Fuzzy-Rough set based methods for attribute reduction is presented here.

Attribute Reduction Based on Approximation Set of Rough Set ⋆

Attribute reduction is one of the core issues of the rough set theory. The traditional method of attribute reduction was designed based on positive region unchanged, as abandoning processing the incompatible data in the boundary domain, so the classification characteristics of the reduction results are not necessarily best. In this paper, the concept of relative approximate degree is proposed i...

Great Deluge Algorithm for Rough Set Attribute Reduction

The process of reducing the number of attributes from an information system is known as attribute reduction problem. The action of attribute reduction problem is an important step of pre-processing in data mining. In the attribute reduction process, reduction is performed with considerations for minimum information loss. Having a dataset with discrete attribute values, it is possible to find a ...

An Innovative Approach for Attribute Reduction in Rough Set Theory

The Rough Sets Theory is used in data mining with emphasis on the treatment of uncertain or vague information. In the case of classification, this theory implicitly calculates reducts of the full set of attributes, eliminating those that are redundant or meaningless. Such reducts may even serve as input to other classifiers other than Rough Sets. The typical high dimensionality of current datab...
