Challenge Problems
Push your limits with advanced challenges
You have a Confusion Matrix with TP=70, TN=50, FP=10, FN=15. Calculate the accuracy, precision, recall, and F1-Score. Discuss the implications if this were a model for a serious disease.
💡 Hint: Calculate each metric step by step using the formulas provided.
Design an experiment to collect data to evaluate a classification model in a case where the Confusion Matrix shows high False Positives. What metrics would you prioritize and why?
💡 Hint: Consider scenarios where high costs associated with positive misclassifications would dictate the prioritization of metrics.
