I hadn't read it before! That's a fascinating result, actually. They emphasize interpretability in the paper, but I find it more interesting that you can do so well with only local information.
My first thought is that it makes sense that averaging together a bunch of local predictions would work well on the ImageNet task, since the different classes tend to have obviously different local textures, and class-relevant information makes up a large part of the image. I would be very curious to see if the technique is as competitive for other tasks.
Yeah, it seems like it would be useful for debugging to replace some part of the architecture with a simple linear sum and see if it does just about as well?
