Generating highly accurate prediction hypotheses through collaborative ensemble learning.

ABSTRACT: Ensemble generation is a natural and convenient way of achieving better generalization performance of learning algorithms by gathering their predictive capabilities. Here, we nurture the idea of ensemble-based learning by combining bagging and boosting for the purpose of binary classification. Since the former improves stability through variance reduction, while the latter ameliorates overfitting, the outcome of a multi-model that combines both strives toward a comprehensive net-balancing of the bias-variance trade-off. To further improve this, we alter the bagged-boosting scheme by introducing collaboration between the multi-model's constituent learners at various levels. This novel stability-guided classification scheme is delivered in two flavours: during or after the boosting process.
