Is there any particular reason for puting Blurpool before the skip-connection layers? about antialiased-cnns HOT 3 OPEN

Hi, I think you're referring to this section: https://github.com/adobe/antialiased-cnns/blob/master/antialiased_cnns/resnet.py#L147-L148, which makes it look like there's blurpool(stride2)->conv(stride1).

Your understanding is correct. It should be conv first. There is actually a conv before it, which was changed from stride 2 to stride 1: https://github.com/adobe/antialiased-cnns/blob/master/antialiased_cnns/resnet.py#L142. So overall, it is conv(stride1) first.

Thank you for your reply! I understand it is conv(stride1) first in the Bottleneck. What I am confused is the skip connections:

Got it, in this case, because there's no non-linearity, the 1x1 conv and NxN blur are interchangeable. It's cheaper to do the blur --> stride --> conv rather than conv --> blur --> stride
