"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. " - Imblance easyensemble

Exploratory Under-Sampling for Class-Imbalance Learning

Witryna我们简单对比一下Easy Ensemble和Balance Cascade的不同之处。首先Easy Ensemble虽然使用了级联的adaboost模型，但是最后分类的时候整个分类器是弱分类器们的并联。. 但是Balance Cascade就不同了，它和GBDT这样的分类器更像，它是逐步的处理误分类的样本，从而提高准确率。 Witryna1 sty 2024 · In order to improve the ability of handling imbalance, EasyEnsemble [11] and Balance-Cascade [11] were proposed and verified to be effective in handling …
