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...
متن کاملFuzzy-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.
متن کاملVariable 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...
متن کاملTabu search for attribute reduction in rough set theory
Attribute reduction of an information system is a key problem in rough set theory and its applications. Using computational intelligence (CI) tools to solve such problems has recently fascinated many researchers. CI tools are practical and robust for many real-world problems, and they are rapidly developed nowadays. However, some classes of CI tools, like memory-based heuristics, have not been ...
متن کاملAn incremental approach to attribute reduction from dynamic incomplete decision systems in rough set theory
Article history: Received 3 August 2013 Received in revised form 15 May 2015 Accepted 22 June 2015 Available online 2 July 2015 Attribute reduction is an important preprocessing step in datamining and knowledge discovery. The effective computation of an attribute reduct has a direct bearing on the efficiency of knowledge acquisition and various related tasks. In real-world applications, some at...
