Discuss the impact of data preprocessing on ensemble learning. How does preprocessing affect the performance of bagging, boosting, and stacking?
A
Data preprocessing improves performance in bagging by reducing noise, in boosting by enhancing feature importance, and in stacking by providing clean inputs for diverse models.
B
Data preprocessing does not affect the performance of ensemble methods. All methods rely on raw, unprocessed data.
C
Data preprocessing increases model complexity and reduces performance in all ensemble methods.
D
Data preprocessing is only relevant for stacking. Bagging and boosting do not benefit from data preprocessing.
