I didn't try OHEM. It is orthogonal. Let me know if you find OHEM works in cascade rcnn.

@zhaoweicai ok, thanks for your reply

@HiKapok Hi, did you try OHEM with cascade rcnn, did OHEM bring any performance gain?
from cascade-rcnn.
@yaoqi-zd no, it's worser with OHEM, I have tried to apply OHEM in the third stage or in all three stage, the former is better, but still worser than the one without OHEM
from cascade-rcnn.
@HiKapok
I have tried to apply OHEM only in the first stage,
dataset: kitti 2d detection
classes: car, pedestrian and cyclist
ohem param:
rois_per_img: 256
performance is sligted better on easy samples but the same on moderate and hard samples.

@yaoqi-zd thank you for your information. I did not get any positive results on my dataset when OHEM is applied.
