Evaluating the Suitability of AUROC and AUPRC Metrics for Binary Classification Tasks with Class Imbalance

The area under the precision-recall curve (AUPRC) is not universally superior to the area under the receiver operating characteristic (AUROC) for evaluating binary classification models in the presence of class imbalance. The choice between AUROC and AUPRC should be guided by the specific context and intended use of the model, rather than solely by the class imbalance.
