Results and Models

The results on COCO 2017 val is shown in the below table. (results on test-dev are usually slightly higher than val).

In the Guided Anchoring paper, score_thr is set to 0.001 in Fast/Faster RCNN and 0.05 in RetinaNet for both baselines and Guided Anchoring.
Performance on COCO test-dev benchmark are shown as follows.
