AI research:NVidia GameGAN replicated a playable PACman game by watching pacman.

[BrianHG]

Do any of you realize how impossibly complicated this achievement actually is.  Just by watching 50k hours of Pacman, no game engine to speak of, graphics engine, sprites, game rules, just a GAN neuronet with inputs and display outputs, it replicated a playable game of Pacman.

GameGAN, a generative adversarial network trained on 50,000 PAC-MAN episodes, produces a fully functional version of the dot-munching classic without an underlying game engine.
