> For example, in 2008, we built I think the first CUDA/GPU deep learning implementation, and helped lead the field to use GPUs.  In 2011, I (Andrew) founded and led the Google Deep Learning team (then called Google Brain) to use Google's cloud to scale up deep learning; and this helped put it on industry's radar.  In 2013, Adam, Bryan Catanzaro and others built the first HPC-style deep learning system, and this helped drive scaling another 1-2 orders of magnitude.
