What Is Deep Learning And How Is It Useful?

Deep learning recently returned to the headlines when Google's AlphaGo program crushed Lee Sedol, one of the highest-ranking Go players in the word. Google has invested heavily in deep learning and AlphaGo is just their latest deep learning project to make the news. Google's search engine, voice recognition system and self-driving cars all rely heavily on deep learning. They've used deep learning networks to build a program that picks out an attractive still from a YouTube video to use as a thumbnail. Late last year Google announced Smart Reply, a deep learning network that writes short email responses for you.
