Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

Consider a dataset with multiple features that contribute equally to the outcome. Discuss how applying L2 regularization might affect the model compared to L1. Which scenario yields a better predictive model?

💡 Hint: Think about the importance of feature selection versus maintaining complexity.

Challenge 2 Hard

You have a dataset with correlated features and suspect that some variables are irrelevant. How would you approach modeling this data using both Lasso and Elastic Net? Discuss your tuning strategy and expected outcomes.

💡 Hint: Consider the benefits of feature selection in model accuracy and interpretability.
