Description

This paper addresses selection as a source of overfitting in Bayesian estimation of distribution algorithms (EDAs). The purpose of the paper is twofold. First, it shows how the selection operator can lead to model overfitting in the Bayesian optimization algorithm (BOA). Second, the metric score that guides the search for
an adequate model structure is modified to take into account the non-uniform distribution of the mating pool generated by tournament selection.
