Which of the following metrics should a Machine Learning Specialist generally use to compare/evaluate machine learning classification models against each other?
Recall
Misclassification rate
Mean absolute percentage error (MAPE)
Area Under the ROC Curve (AUC)
Explanations:
Recall is a performance metric that measures the ability of a model to find all relevant cases (true positives) in a dataset. While it is important, it is not sufficient alone for comparing models as it does not consider false positives.
The misclassification rate is the fraction of incorrect predictions made by the model. While it provides useful information about the model’s accuracy, it does not capture the trade-offs between different types of errors effectively.
Mean Absolute Percentage Error (MAPE) is primarily used for regression problems to measure prediction accuracy in percentage terms. It is not applicable for evaluating classification models, which makes it unsuitable for this context.
Area Under the ROC Curve (AUC) is a robust metric for evaluating classification models, as it considers the true positive rate and false positive rate across different threshold values, providing a comprehensive view of model performance.
