An аutоmаted system flаgs оrders. Each flagged оrder triggers an expensive personal concierge call. Logistic regression has recall 0.89 and precision 0.47. Gradient boosting has recall 0.73 and precision 0.55. Which is the better choice? (Refresh from lessons) Table 5.6.1: Metrics Trade-off in Classification Metric Guidance on When to Use this Metric Accuracy Use as a rough indicator of model training progress/convergence for balanced datasets.* For model performance, use only in combination with other metrics. Avoid for imbalanced datasets*. Consider using another metric. Recall (Sensitivity, True positive rate) Use when false negatives are more expensive than false positives. False positive rate Use when false positives are more expensive than false negatives. Precision Use when it's very important for positive predictions to be accurate.
