ABC-based stacking method for multilabel classification

Abstract

Multilabel classification is a supervised learning problem wherein each individual instance is associatedwith multiple labels. Ensemble methods are effective in managing multilabel classification problems by creating aset of accurate, diverse classifiers and then combining their outputs to produce classifications. This paper presents anovel stacking-based ensemble algorithm, ABC-based stacking, for multilabel classification. The artificial bee colonyalgorithm, along with a single-layer artificial neural network, is used to find suitable meta-level classifier configurations.The optimization goal of the meta-level classifier is to maximize the average accuracy of classification of all the instancesinvolved. We run an experiment on 10 benchmark datasets of varying domains and compare the proposed approach tofive other ensemble algorithms to demonstrate the feasibility and effectiveness of ABC-based stacking.
