Deep Learning needs deep theory too !

Deep learning enthusiam is based on applied researches of a huge community, coming from both the academic and industrial side. In this ecosystem, 3 researchers has become very popular: Yoshua Bengio (McGill University), Geoffrey Hinton (Google) and Yann Le Cun (Facebook). These three authors has co-published in the journal Nature a review on deep learning (part of a "Nature Insight" supplement on Machine Intelligence, with another interesting paper by Michael Littman about Reinforcement Learning). These increasing attention about deep learning make Neural networks, and Convolutional Neural Nets very popular and manipulated by a huge community of coders. Test and learn engineering has been experimented in several places of the world, ranging from Toronto, New-York, Paris or San Francisco.
