Created page with "{{see also|Machine learning terms}} ==Introduction== In the field of machine learning, the evaluation of classification models is a critical task. One common metric used to measure the performance of such models is the PR AUC, or Area Under the Precision-Recall (PR) Curve. The PR AUC is particularly useful when dealing with imbalanced datasets, where the proportion of positive and negative samples is unequal. ==Precision-Recall Curve== ===Definition=== The Precision-..."
