Abstract

The widespread use of artificial neural networks and the difficult work regarding the correct specification (tuning) of parameters for a given problem are the main aspects that motivated the approach purposed in this paper. This approach employs an evolutionary search to perform the simultaneous tuning of initial weights, transfer functions, architectures and learning rules (learning algorithm parameters). Experiments were performed and the results demonstrate that the method is able to find efficient networks with satisfactory generalization in a shorter search time.
