I found un-fair data usage

[mandal4]

Hi there.
I well read uploaded source code. I found you set k-shot masked sample with k-'image' not 'instance'.
It might be okay that there is binary mask for input of PRN.
But the same k-'image' is fed into fasterRCNN in 2nd phase. So for FasterRCNN, it could be k+1 shot or k+2 shot and so on because you set k-shot with image-wise.
Unfortunately i think it is un-fair setting for few-shot learning.
Could you explain about it? I hope i misunderstood your nice work.

Hello, we have filtered the images with k-shot instance. Please see the function

MetaR-CNN/lib/roi_data_layer/roidb.py

Line 61 in 0e54c48

Thanks for reply. I confused that. But still i couldn't understand it is same for input of PRN

I have the same concern with you and I have create an issue on the top. Maybe you can check that. I think I express the same idea with you.

I also find weird modeling. After the reweighted feature, it also produce num_classes+1 prediction. So what's the contribution of feature reweighting?
