Deep learning is currently the hottest topic in machine learning and artificial intelligence. In the first part of this seminar I will review the concept of deep learning and how it has started a new era in the field of machine learning. In the second part, I will illustrate our efforts to replicate the celebrated result of DeepMind about algorithms that learn to play videogames at superhuman level. Finally, I will mingle some physics and deep learning concepts to provide some discussion on future applications.
