Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

Create a dataset that follows a non-linear trend and use polynomial regression to model it. Visualize the fit and discuss any patterns you observe.

💡 Hint: Remember to check for any signs of overfitting or underfitting in the graph.

Challenge 2 Hard

Discuss how polynomial regression can be combined with regularization techniques to prevent overfitting. Provide specific examples of these techniques.

💡 Hint: Think about how adding penalties affects the complexity of the model.
