AUC_weighted is a Classification metric. Note: AUC is the Area under the Receiver Operating Characteristic Curve. Weighted is the arithmetic mean of the score for each class, weighted by the number of true instances in each class. Incorrect Answers: A: normalized_mean_absolute_error is a regression metric, not a classification metric. C: When comparing approaches to imbalanced classification problems, consider using metrics beyond accuracy such as recall, precision, and AUROC. It may be that switching the metric you optimize for during parameter selection or model selection is enough to provide desirable performance detecting the minority class. D: normalized_root_mean_squared_error is a regression metric, not a classification metric. Reference: https://docs.microsoft.com/en-us/azure/machine-learning/how-to-understand-automated-ml
