Earlier this week TechCrunch broke the news that Google had acquired Geoff Hinton’s recently founded deep learning startup. Soon thereafter Geoff posted on his Google+ page an announcement confirming the news and his (part-time) departure to Google from the University of Toronto. From the details that have emerged so far, it appears that he will split his time between UoT and the Google offices in Toronto and Mountain View. What does Geoff’s move, and other recent higher profiles departures, say about the future of machine learning research in academia? A lot, I think.
