Fig.4 Learning curves of YOLO-V5x train/val/box_loss:bounding box detection loss of training set/testing set;train/val/obj_loss:objects detection loss of training set/testing set;train/val/cls_loss:Classification loss of training set/testing set.mAP_0.5:0.95:denotes the mean mAP at the IoU threshold of 0.5~0.95 (from 0.5 to 0.95,step width 0.05,that is 0.5,0.55,0.6,0.65,0.7,0.75,0.8,0.85,0.9,0.95).mAP_0.5:mAP with IoU threshold set at 0.5.
