Why use the proposal of an unknown class to regress the gt box of a known class

Thanks for your greate job!
I don't know if I understand correctly. In roi_head stage, is it reasonable to use the proposal of the unknown class to regress the gt box of the known class with the lowest IOU

I am also confused about this

The proposals that are auto-labelled as unknowns are used only in the contrastive clustering. It is used to learn the classification/regression head. Does this resolve the confusion?

Please re-open this issue for more discussion.

hi there,
The proposals that are auto-labelled as unknowns are still used to train the regression head in the code? Is there something improper that the unknown proposals have a corresponding gt boxes to regress?
