Witryna27 kwi 2024 · 1 Answer. Sorted by: 1. In simple words, you need to check if there is an imbalance in the classes present in your target variable. For example: If you check the ratio between DEATH_EVENT=1 and DEATH_EVENT=0, it is 2:1 which means our dataset is imbalanced. To balance, we can either oversample or undersample the data. Witrynaimbalanced-ensemble, abbreviated as imbens, is an open-source Python toolbox for quick implementing and deploying ensemble learning algorithms on class-imbalanced data.
