Google taught DeepMind to play Atari games all on its own, but letting humans help may be faster, according to researchers from Microsoft and Germany. They invited folks of varying skills to play five Atari 2600 titles: Ms. Pac-Man, Space Invaders, Video Pinball, Q*Bert and Montezuma's Revenge. After watching 45 hours of human gameplay, the algorithm could beat its mentors at pinball, though it struggled at Montezuma's revenge -- just as Deepmind did. Unlike with DeepMind's trial-and-error methods (below), however, the human-aided AI learned to play the games in less time than other AI systems. "Current state-of-the-art approaches require millions of training samples," the paper states.
