Question 1

What happens when you set a small value for the regularization parameter 'C' in SVM?

The model becomes overly complex
The model generalizes broadly
The model memorizes the training data

💡 Hint: Think about what broad versus narrow margins mean for classification.

Question 2

Is Gini impurity always lower than or equal to 1?

True
False

💡 Hint: What would a Gini value of 1 indicate?

Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

Given a dataset with overlapping classes, describe how you would use SVM to achieve better classification accuracy. What steps would you take to select the appropriate kernel and tune parameters?

💡 Hint: Think about evaluating model performance on a validation set before finalizing.

Challenge 2 Hard

Explain how you would address the issue of overfitting when using Decision Trees on a complex dataset.

💡 Hint: What specific criteria might you impose on the Growth of the tree?
