metric is only focusing on Intersection over Union (IoU) over 50, i.e. AP⁵⁰. However, COCO dataset evaluate AP over a range of IoU from 50 to 95. In original Fast R-CNN, the loss function only focus on optimizing AP⁵⁰: The first term Lcls is the classification log loss while the second term Lloc is
