Challenge Problems
Push your limits with advanced challenges
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.
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.
