Re:Why do CNNs generalize so poorly to small image transform...

The paper claims the opposite: "[...] jaggedness is greater for the modern, deeper, networks compared to the less modern VGG16 network. While the deeper networks have better test accuracy, they are also less invariant."
>While VGG16 has 5 pooling operations in its 16 layers, Resnet50 has only one pooling operation among its 50 intermediate layers and InceptionResnetV2 has only 5 among its intermediate 134 layers.
Aka being computationally cheap with pooling causes weird sampling issues.
The paper has a terrible pompous title that's just wrong. Modern CNNs generalize wonderfully on small translations. They just managed to break a couple of old CNNs and go on to claim they broke AI research or something.
