Why is the global average pooling layer disabled? #29

Hello,

Thank you for your great work. I have a question regarding the architecture of neural network. You disable the last global average pooling layer that is normally used in ResNet. Why is this? The reasoning behind this does not appear to be mentioned in either PVNet or your work.

Regards,

I forgot to mention that my assumption is that global average pooling flattens the feature map, which is an unwanted property become the upsampling stage.

EDIT: I got a response on the PVNet github. My assumption was correct.
