%description
Four ensemble-based methods (SMOTEBoost, RUSBoost, UnderBagging, and
SMOTEBagging) for class imbalance problem are implemented for binary
classification. Such methods adopt ensemble methods and data re-sampling
techniques to improve model performance in presence of class imbalance
problem. One special feature offers the possibility to choose multiple
supervised learning algorithms to build weak learners within ensemble
models. References: Nitesh V. Chawla, Aleksandar Lazarevic, Lawrence O.
