Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

Consider a classification model that outputs the following probabilities for three classes: Class A: 0.6, Class B: 0.3, Class C: 0.1. If the true class is Class B, calculate the cross-entropy loss.

💡 Hint: Substitute the predicted probabilities into the formula carefully.

Challenge 2 Hard

Explain a scenario in which cross-entropy loss would be favored over mean squared error in a model training context.

💡 Hint: Think of how classification problems differ from regression.
