Witryna23 lip 2024 · Decision trees frequently perform well on imbalanced data. In modern machine learning, tree ensembles (Random Forests, Gradient Boosted Trees, etc.) almost always outperform singular decision trees, so we’ll jump right into those: Tree base algorithm work by learning a hierarchy of if/else questions. This can force both … Witryna14 kwi 2024 · In many real world settings, imbalanced data impedes model performance of learning algorithms, like neural networks, mostly for rare cases. This is especially problematic for tasks focusing on ...
