Challenge Problems
Push your limits with challenges.
Question 1
A regression model predicts temperatures for a week. Actual temperatures are [70, 72, 68, 65, 71] degrees, and predicted temperatures are [68, 74, 67, 66, 69]. Calculate the MSE.
💡 Hint: Apply the MSE formula step by step.
Question 2
A model is trained for image classification. If the predicted probabilities for a cat class are [0.8, 0.1, 0.2] and the actual classes are [1, 0, 1], calculate the binary cross-entropy loss.
💡 Hint: Use the cross-entropy formula carefully considering the probabilities.
