Grid Effects #22

Closed WesRobbins closed 2 years ago

WesRobbins commented 2 years ago

I am only getting strong activations along a grid pattern. Attached image shows 1,000 averaged activation maps which highlights grid. Is there a known reason for this effect?

I am using a standard resnet implementation with dilation set to 1 on all conv layers grid-activations

What is the original input? Is it a checkerboard？

It looks weird. What is the classifier?
