An Attribute Reduction Algorithm Based on Rough Set Theory and an Improved Genetic Algorithm
Because the existing attribute reduction algorithms based on rough set theory and genetic algorithm have the main problems: the complexity in calculating fitness function and slow speed in convergence. An attribute reduction algorithm based on rough set theory and an improved genetic algorithm is proposed in this paper. In order to simplify the calculation of fitness function under the conditio...
متن کاملAn enhanced classification method comprising a genetic algorithm, rough set theory and a modified PBMF-index function
This study proposes a method, designated as the GRP-index method, for the classification of continuous value datasets in which the instances do not provide any class information and may be imprecise and uncertain. The proposed method discretizes the values of the individual attributes within the dataset and achieves both the optimal number of clusters and the optimal classification accuracy. Th...
متن کاملHybrid of genetic algorithm and great deluge algorithm for rough set attribute reduction
Abstract: The attribute reduction problem is the process of reducing unimportant attributes from a decision system to decrease the difficulty of data mining or knowledge discovery tasks. Many algorithms have been used to optimize this problem in rough set theory. The genetic algorithm (GA) is one of the algorithms that has already been applied to optimize this problem. This paper proposes 2 kin...
متن کاملAn Improved Genetic Algorithm for Attribute Reduction in Rough Set Theory
Since attribute reduction is NP-hard problem, in order to obtain the minimum relative reduction effectively in decision table, an attribute reduction algorithm in rough set theory based on improved genetic algorithm is proposed. At first, the dependence concept of decision attribute on condition attribute is introduced. At the same time, the relative importance of the condition attribute with r...
متن کاملA Clustering Algorithm Based on Rough Set and Genetic Algorithm
With the development of computer and information technology, the capacity of data and information is increasing. The processing of data and information becomes the hot issue in the current scientific community. Rough set and genetic algorithm are two data mining and processing technologies which had been commonly used. Rough set can process data quickly and the algorithm is simple. The converge...
