EUSBoost: Enhancing ensembles for highly imbalanced data-sets by evolutionary undersampling
作者:
Highlights:
• A new ensemble solution for the class-imbalance problem is proposed.
• The accuracy of the base classifiers is enhanced by evolutionary undersampling.
• A diversity exploitation mechanism is developed, which is useful to deal with imbalance.
• EUSBoost outperforms the state-of-the-art ensembles in highly imbalanced data-sets.
• EUSBoost behavior is explained via kappa-AUC error diagrams.
