WebAug 6, 2024 · F1 Score. F1 score is HM (Harmonic Mean) of precision and recall. AP. The general definition for the Average Precision(AP) is finding the area under the precision-recall curve. mAP. The mAP for object detection is the average of the AP calculated for all the classes. [email protected] means that it is the mAP calculated at IOU threshold 0.5. WebNov 2, 2024 · Recall = TP/ (TP + FN) and Precision = TP/ (TP + FP). Now we can simplify the appearance of the F1 Score formula by using “Recall” and “Precision” in place of all the TP, TN, FP, FN formulas).
