A model predicts 200 instances as positive, of which 150 are actual positives, but 50 are false positives. If the model is used in a fraud detection scenario, discuss the implications of this precision level.
💡 Hint: Consider the potential consequences of false positives and customer trust.
In a different model where high precision is maintained over time, what could you suggest as maintenance practices to ensure this precision stays high?
💡 Hint: Think about how real-world changes can affect model performance.
