Abstract

A novel approach for applying Genetic Algorithms tothe configuration of Radial Basis Function Networks is presented.A new crossover operator that allows for some controlover the competing conventions problem is introduced.Besides it, a minimalist initialization scheme which tends togenerate more parsimonious models is also presented. Finally,a reformulation of Generalized Cross-Validation criterionfor model selection, making it more conservative, isdiscussed. The proposed model is submitted to a computationalexperiment in order to verify its effectiveness.Keywords: Radial Basis Function Networks , GeneticAlgorithms
