Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

You have a model with an AUC of 0.85. Briefly explain what this tells you about the model, and whether it suffices for fraud detection purposes.

💡 Hint: Consider the impacts of false negatives in fraud cases.

Challenge 2 Hard

Create an ROC curve using hypothetical true positive and false positive values, and explain how you would interpret the shape and area.

💡 Hint: Think about how each plotted point influences the overall evaluation of the classifier.
