Challenge Problems

Push your limits with challenges.

Question 1

Suppose you have a dataset with a class imbalance where 90% are negatives and only 10% are positives. If your model predicts all of them as negative, what would be the accuracy, precision, recall, and F1 Score?

💡 Hint: Calculate each metric based on the confusion matrix components.

Question 2

Analyze a classification model that generates the following confusion matrix: TP=25, TN=15, FP=5, FN=5. What are the accuracy, precision, recall, and F1 score?

💡 Hint: Follow the definitions of each metric to guide your computations.
