Question 1

What is overfitting in Decision Trees?

Model learning the training data too well
Model generalizing well
Model being too simplistic

💡 Hint: Consider how well the model performs on new data.

Question 2

True or False: Pre-pruning only occurs after a decision tree is fully grown.

True
False

💡 Hint: Think about when the decision to stop growing the tree is made.

Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

You have a dataset with many outliers. Discuss how you would use Decision Trees and pruning techniques to develop a predictive model while minimizing overfitting.

💡 Hint: Consider how pruning can balance bias and variance while dealing with complex datasets.

Challenge 2 Hard

Create a scenario where a Decision Tree fails due to overfitting, detailing how applying both pre-pruning and post-pruning could help rectify the issue.

💡 Hint: Reflect on how noise affects splits and how pruning might correct excessive complexity.
