Which of the following metrics should a Machine Learning Specialist generally use to compare/evaluate machine learning classification models against each other?
A . Recall
B . Misclassification rate
C . Mean absolute percentage error (MAPE)
D . Area Under the ROC Curve (AUC)

View Answer

Answer: D

Explanation:

Area Under the ROC Curve (AUC) is a metric that measures the performance of a binary classifier across all possible thresholds. It is also known as the probability that a randomly chosen positive example will be ranked higher than a randomly chosen negative example by the classifier. AUC is a good metric to compare different classification models because it is independent of the class distribution and the decision threshold. It also captures both the sensitivity (true positive rate) and the specificity (true negative rate) of the model.
