Challenge Problems
Push your limits with challenges.
Question 1
You are given a dataset with 90% healthy patients and 10% patients with a rare condition. How would you apply instance re-weighting to improve the model's predictive accuracy on the rare condition?
💡 Hint: Focus on changing how the model treats the rare versus common classes.
Question 2
Discuss a case where implementing instance re-weighting without thorough testing might result in a biased model. How could such biases be identified post-implementation?
💡 Hint: Think about varying results in different demographic segments.
