Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

You have two models: Model A with high bias and Model B with high variance. Your dataset has a complex underlying structure. Which model would you prefer if your goal is to generalize well? Provide reasoning.

💡 Hint: Consider what each model distinctly can learn from the complexity.

Challenge 2 Hard

Suppose you are working on a classification problem with imbalanced data (many instances of one class and very few of another). How does this scenario affect your bias-variance trade-off, and what measures could you take?

💡 Hint: Reflect on how class representation influences learning.
