WebSep 1, 2024 · In computer vision, mean average precision (mAP) is used as a standard metric to evaluate the accuracy of object detection algorithms. In the precision-recall … WebCompute average precision (AP) from prediction scores. AP summarizes a precision-recall curve as the weighted mean of precisions achieved at each threshold, with the increase in recall from the previous threshold used as the weight: AP = ∑ n ( R n − R n − 1) P n. where P n and R n are the precision and recall at the nth threshold [1 ...
