Challenge Problems
Push your limits with challenges.
Question 1
Imagine you are developing a model for fraud detection. Describe the impact of high variance on model performance and suggest methods to mitigate this issue.
💡 Hint: Reflect on what happens when a model learns too many rules from the training set.
Question 2
Consider a scenario where you have a linear regression model that is consistently underperforming. What steps can you take to evaluate whether the model is suffering from bias or variance?
💡 Hint: Analyze what happens during training versus testing.
