I visited Google DeepMind on Friday (17 Oct). I gave a talk on neural machine translation and met many researchers, including some of my former colleagues such as Razvan Pascanu and Guillaume Desjardins.
As can be expected, I signed NDA before my visit and cannot discuss much about any interesting things that I have heard and discussed at DeepMind. But, I can tell one thing: despite my constant attempt, none of the researchers there was able to tell me a single downside (even when they were quite drunk!). Incredible!
Anyways, it was a very interesting and exciting day.
