Some features help to find useful clusters whereas others may hinder the clustering process. In other words, some selected features can provide better clusters. Besides, the feature selection process also allows the reduction of the dataset dimensionality, improving the clustering method efficiency. This work describes a Bayesian feature selection approach for a Clustering Genetic Algorithm (CGA). The general method can be described by means of four steps: (i) apply the CGA to some selected objects (sample) of the complete dataset; (ii) consider that the obtained clusters form different classes, which can be modeled by Bayesian networks; (iii)
