A multi-objective optimization design framework for ensemble generation

Published: 06 July 2018 Publication History

Abstract

Machine learning algorithms have found to be useful for the solution of complex engineering problems. However, due to problem's characteristics, such as class imbalance, classical methods may not be formidable. The authors believe that the application of multi-objective optimization design can improve the results of machine learning algorithms on such scenarios. Thus, this paper proposes a novel methodology for the creation of ensembles of classifiers. To do so, a multi-objective optimization design approach composed of two steps is used. The first step focus on generating a set of diverse classifiers, while the second step focus on the selection of such classifiers as ensemble members. The proposed method is tested on a real-world competition data set, using both decision trees and logistic regression classifiers. Results show that the ensembles created with such technique outperform the best ensemble members.
