Dear daijifeng: when I write the first-stage rpn prototxt, do I need add the OHEM layers to the first-stage rpn prototxt?
(I want use OHEM to do hard examples mining).

By the way, Is it possible to share your rpn prototxt to me? ^_^

daijifeng001 commented 8 years ago

No, OHEM is not applied to RPN. You can send me an email for the prototxt.

@daijifeng001

why not used ohem for rpn? rpn also adopts heuristic ways to random pick fg/bg rois for the softmax loss.
