If you use computer generated images to teach your networks, you have a nice network for computer generated images. It might be good to pre-train a net (instead of random weights), but you still need labeling of real world images. E.g., a guy once trained a self driving car model in GTA 5. I’m sure this algorithm won’t do great in the real world.
But I already see an industry forming, promising to get rid of all labeled data. And there will be idiots believing it. That’s how all the Silicon Valley startups work. Unicorns on Powerpoint slides and an empty basket in reality. (src: living and working in the valley)
