Topographic DNNs

The visual system is composed of neurons embedded in detailed topographic maps. Although the past few years have seen huge advances in our ability to predict the activity of neurons in these maps with deep neural networks, models of the structure of the maps themselves is lacking. I'm using deep convolutional neural networks to better understand 1) the role of this functional architecture and 2) how it might develop in the brain.
