The second day was a bit better and I didn't get a mousson rain shower as opposed to yesterday. The opening keynote by the former AI Facebook person was interesting, but if you are into science, CV, ML, DL for a few years there were nothing new. The conference is mostly marketing you could feel that only a few people got what the speaker intended to present, at least those same people got in their heads new buzz words.
The overall observation was a lot of queueing and not enough places in the various conference room. There are zillion of satellite events around but again mostly marketing events.
But you can still meet interesting people, I guess.
