Abstract

This paper presents a novel ensemble construction approach based on Artificial Immune Systems (AIS) to solve regression problems. Over the last few years AIS have increasingly attracted interest from researchers due to their ability to balance the exploration and exploitation of the search space. Nevertheless, there have been just a few applications of those algorithms in the construction of committee machines. In this paper, a population of feed-forward neural networks is evolved using the Clonal Selection Algorithm and then ensembles are automatically composed of a subset of this neural network population. Results show that the proposed algorithm can achieve good generalization performance on some hard benchmark regression problems.
