Precision-Recall (P-R) curves for the average of the 5 L1-folds. The blue lines refer to the results from our AI strategy; the red lines refer to the results from the LR algorithm. Different rows refer to different accumulation precipitation intervals; different columns refer to calibration and regionalization. Each panel also displays the AUC index of the P-R curve along with the corresponding value derived from the prevalence-based random model (dotted line), which serves as a benchmark.
