| Abstract |
Extreme learning machine (ELM) has shown to be a suitable algorithm for\n classification problems. Several ensemble meta-algorithms have been\n developed in order to generalize the results of ELM models. Ensemble\n approaches introduced in the ELM literature mainly come from boosting\n and bagging frameworks. The generalization of these methods relies on\n data sampling procedures, under the assumption that training data are\n heterogeneously enough to set up diverse base learners. The proposed ELM\n ensemble model overcomes this strong assumption by using the negative\n correlation learning (NCL) framework. An alternative diversity metric\n based on the orthogonality of the outputs is proposed. The error\n function formulation allows us to develop an analytical solution to the\n parameters of the ELM base learners, which significantly reduce the\n computational burden of the standard NCL ensemble method. The proposed\n ensemble method has been validated by an experimental study with a\n variety of benchmark datasets, comparing it with the existing ensemble\n methods in ELM. Finally, the proposed method statistically outperforms\n the comparison ensemble methods in accuracy, also reporting a\n competitive computational burden (specially if compared to the baseline\n NCL-inspired method). |
