> the highest profile people work for the big companies and don’t share their discoveries
I have to strongly disagree with this for the specific case of AI/ML. The big company labs are publishing open access papers non-stop, often with code and sometimes even datasets. They're more open than some areas of academia, in fact.
Really? I heard the opposite from someone in the field, who told me that they do publish but it is never the really relevant stuff. I can’t really judge that myself to be honest
I work in the field. New and relevant stuff is published frequently by Google, Facebook and Microsoft (as well as smaller companies like NVidia etc). Apple very occasionally publishes too.
Leon Gatys, the guy who published A Neural Algorithm for Artistic Style that revolutionized the entire industry while he was at a university is now employed at Apple. They have published at least one thing that was semi-interesting on cognitive functioning in older adults and how it can be expressed through smartphone usage: http://delivery.acm.org/10.1145/3310000/3300398/a168-gordon....
Interesting and certainly compelling, but not earth-shaking like style transfer has been.
