The Core Idea
Deep learning relies on representing data across layered feature spaces.
By combining multiple models, ensemble methods can achieve higher accuracy and robustness than individual models.
Example: Imagine two learners predicting house prices – one slightly o

Frequently asked questions
What is cross-validation?
Cross-Validation: Use cross-validation to evaluate the meta-model’s performance and tune its hyperparameters.
How does regularization help model stacking?
Regularization: Use regularization techniques like L1 or L2 regularization to prevent overfitting.
What is dropout, and how does it relate to neural networks?
Dropout: Dropout is a technique that randomly drops out neurons during training - this can help prevent overfitting in neural networks.
What are the key metrics for evaluating stacking ensembles?
