Answer: Stacking combines predictions from multiple models, improving performance but increasing complexity. Stacking is effective in scenarios with diverse models and complex relationships.
Stacking combines predictions from multiple models, often using a meta-model, which can improve overall performance by leveraging diverse models and capturing complex relationships. The main advantage of stacking is its ability to integrate different types of models, potentially leading to better predictive accuracy. However, it also increases model complexity and can be computationally intensive. Stacking is most effective in scenarios where there are diverse models and complex relationships that need to be captured.
