what about the speed and mAP vs yolov3

[zhuqiang00099]

@HiKapok hi, have you ever try to train on COCO ? can the model be as good as the paper result (we can find its' mAP is close to yolov3, but 3 times fps to yolov2). Recently, I want to do human head detection, i want to use light-head-rcnn, can you give some advices? I am new in deep learning,thank you.
