Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

Create a decision tree model for a dataset with many overlapping classes. Define your pre-pruning strategy.

💡 Hint: Focus on how many samples should reliably inform your splits.

Challenge 2 Hard

Analyze the effects of no pre-pruning on training versus test accuracy in a decision tree.

💡 Hint: Look for divergences in performance metrics.
