(rows 5–10). OHEM (rows 11–13) improves mAP by 2.4 points compared to FRCN with the bg_lo = 0.1 heuristic for VGGM, and 4.8 points without the heuristic. This result demonstrates the sub-optimality of these heuristics and the effectiveness of our hard mining approach. Training loss using VGG16 OHEM
