Challenge Problems
Push your limits with advanced challenges
You are given a dataset with a large number of features, some of which are likely irrelevant. Explain how you would determine whether to use Lasso, Ridge, or Elastic Net regularization in your model. Justify your choice based on the characteristics of your dataset.
💡 Hint: Think about the nature of the features you are dealing with.
Assess how cross-validation alters the evaluation of a model compared to a single train-test split. What are some key metrics you might observe that illustrate better performance reliability?
💡 Hint: Consider how repeated evaluations minimize errors that might stem from random data allocation.
