Jeff Dean, Greg Corrado & Andrew Ng Begin the Google Brain Deep Learning AI Research Projects

In 2011 Google Fellow Jeff Dean, Google Researcher Greg Corrado, and Stanford University professor Andrew Ng
founded the deep learning artificial intelligence research team at Google known in 2020 as Google Brain. Ng had been interested in using deep learning techniques to crack the problem of artificial intelligence since 2006, and in 2011 began collaborating with Dean and Corrado to build a large-scale deep learning software system, DistBelief,^[7] on top of Google's cloud computing infrastructure. Google Brain started as a Google X project and became so successful that it was graduated back to Google.
n March 2013, Google hired Geoffrey Hinton, a leading researcher in the deep learning field, and acquired the company DNNResearch Inc. headed by Hinton.

According to the Wikipedia article on Google Brain accessed in November 2020, Google Brain areas of research included Artificial Intelligence-Devised Encryption Systems, Image Enhancement using neural networks to fill in details in very low resolution pictures, Google Translate (Google Neural Machine Translation (GNMT), Robotics. Google Products in which Google Brain research was then applied were "the  Android Operating System's speech recognition system,^[21] photo search for Google+^[22] and video recommendations in YouTube.^[23]"
