Your question is Measuring Model Performance. Take a moment with it on the right.
Talk me through your thinking if you like. When you're confident, submit your answer and I'll grade it like a real screen (7/10 or better passes).
How would you measure the performance of a model?
Explain how your evaluation approach would differ for classification, regression, ranking, or probabilistic models. Address metric selection, validation data, class imbalance, threshold decisions, calibration, and error analysis. Focus on how you would connect offline metrics to the model’s intended real-world outcome.
