Challenge Problems
Push your limits with challenges.
Question 1
Imagine you’re developing a medical diagnosis system. You find that your model has precision = 0.85 and recall = 0.4. How would this affect your decision to implement the model? Calculate the F1 Score and discuss if you would proceed or improve the model.
💡 Hint: Consider both practical and ethical implications in a medical context.
Question 2
A company analyzes the results of two models. Model A has Precision = 0.7 and Recall = 0.6, while Model B has Precision = 0.6 and Recall = 0.7. Calculate the F1 Scores for both models. Which model should the company choose, and why?
💡 Hint: Pay attention to how precision and recall interact to produce the F1 Score.
