The Masterclass on Deep Learning will not only discuss the layers of the convolutional networks and the application of modern Deep Learning tools, but will go further. We will discuss the intrinsic mechanisms of the black box: the essential notion of representation learning, and the neuro-mathematics of self-organization and contextual processing. We will take a deep tour into modern vision and brain research, both in the retina as visual cortex, and realize the strong similarities between the visual pathway and Deep Learning, and how much be learned from one by studying the other. We demonstrate surgical software tools to dissect the network layers and look inside what they compute, and explain modern visualization tools, like t-SNE.

All essential mathematics is explained in an intuitive way, with many visual and hands-on examples.

The masterclass can be followed by all interested in deep learning, with an emphasis on trying to understand what happens inside. All code of all examples is given to the participants.
