The basics of Deep Learning and Bayesian Networks in under five minutes

Still confused about deep learning, how it works, what is its shortcomings, and what is its origins? Paraphrasing Zoubin: Deep learning is neural networks rebranded. Compute power enables us to run many layers of weighted computational neurons, hence the phrase "deep". They are data hungry, computationally intensive, uninterpretable black boxes that can be easily fooled. But ... They can do amazing things and using them is becoming easier.
