WitrynaThe EasyEnsemble method independently bootstraps some subsets of the majority class. Each of these subsets is supposedly equal in size to the minority class. Then, a classifier is trained on each combination of the minority data and a subset of the majority data. The final result is then the aggregation of all classifiers.
