Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

You have two models: Model A shows signs of overfitting, while Model B shows underfitting. Propose a regularization strategy for each model and justify your choices.

💡 Hint: Think about the nature of the problems each model is facing.

Challenge 2 Hard

Differentiate the results obtained through K-Fold cross-validation vs a simple train/test split in a project. Provide a detailed analysis discussing reliability measures.

💡 Hint: Consider the validity of performance assessments.
