Challenge Problems
Push your limits with challenges.
Question 1
Consider a dataset where you notice your decision tree is performing excellently on training data but poorly on validation data. How would you approach pruning, and what steps would you take?
💡 Hint: Consult performance metrics to inform your pruning decisions.
Question 2
Imagine you have a decision tree with many splits leading to small, specific rules to classify data. How can pre-pruning aid in improving the model's generalization?
💡 Hint: Think about how stopping growth early can impact complexity.
