detach during salient mode #74
Comments
During jointly training with edge, we try to use the edge features
extracted from the edge branch to help refine the details around the edge
areas of the salient features.
By detaching the edge features, we can avoid the influence caused by the
supervision information from the salient branch, as the edge branch aims to
learn all possible edge areas while the salient branch only cares the
salient objects.

… Hi:
Nice Work.
I notice that you detach the backprop after block layers when training
your joint_poolnet with mode == 1, which is the salient mode. So the
deeppool layer and your backbone only gets update during the edge mode. Can
you explain the reason behind it?
Thank you.

I understand your idea, but all the parameters of backbone/convert_layers/deep_pool_layers will not be updated from salinet branch right? The objective of this network is salient object segmentation, and the majority of the parameters of the network will not be update from salinet obj segmentation task. I'm still confused by this |
It will be updated by this line
