- True
- False
Show hintHide hint
Think about the purpose of a meta-model.
Question 5.
Given a classification task, propose a stacking strategy using at least three different models. Describe how you would set up the training and evaluation.
Show hintHide hint
Think about model diversity and evaluation metrics.
Question 6.
