Abstract
Two ensemble methods, bagging and boosting, were investigated for improving algorithm performance. The authors´ results confirmed the theoretical explanation of L. Breiman (1996) that bagging improves unstable, but not stable, learning algorithms. While boosting enhanced accuracy of a weak learner, its behavior is subject to the characteristics of each learning algorithm
