Abstract

Training an ensemble of neural networks is an interesting way to build a Multi-net System. One of the key factors to design an ensemble is how to combine the networks to give a single output. Although there are some important methods to build ensembles, Boostingis one of the most important ones. Most of methods based on Boostinguse an specific combiner (Boosting Combiner). Although the Boosting combinerprovides good results on boosting ensembles, the results of previouses papers show that the simple combiner Output Averagecan work better than the Boosting combiner. In this paper, we study the performance of sixteen different combination methods for ensembles previously trained with Adaptive Boostingand Average Boosting. The results show that the accuracy of the ensembles trained with these original boosting methods can be improved by using the appropriate alternative combiner.
