WebJun 7, 2024 · Ensemble methods combine multiple base estimators in order produce more robust models, that generalize better in new data. Bagging and Boosting are two main … WebApr 23, 2024 · Weak learners can be combined to get a model with better performances. The way to combine base models should be adapted to their types. Low bias and high variance weak models should be combined in a way that makes the strong model more robust whereas low variance and high bias base models better be combined in a way that makes … Webe.
