In our previous study, a grouping-geneticalgorithm- based (GGA-based) attribute clustering process has been proposed for grouping features. In this paper, we further improve its performance and propose a center-based GGA for attribute clustering (CGGA). A new encoding scheme with corresponding crossover and mutation operators are designed, and an improved fitness function is proposed to achieve better...
In the past, the concept of performing the task of feature selection by attribute clustering was proposed. Hong et al. thus proposed several genetic algorithms for finding appropriate attribute clusters. In this paper, we attempt to improve the performance of the GA-based attribute-clustering process based on the grouping genetic algorithm (GGA). In our approach, the general GGA representation and...
