Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

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.

Challenge 2 Hard

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.
