Briefly discuss the various Ensemble methods.
Ensemble methods in machine learning involve combining multiple models to improve predictive performance compared to any individual model. Here's a brief overview of some popular ensemble methods:
1. Bagging (Bootstrap Aggregating): Bagging involves training multiple instances of the same base model on different subsets of the training data, typically sampled with replacement. These models are then averaged (for ________ _______ _______ ______ __________.
