Predictions for Artificial Intelligence in 2018 Positive reinforcement Reinforcement learning takes inspiration from the ways that animals learn how certain behaviors tend to result in a positive or negative outcome. Using this approach, a computer can say, figure out how to navigate a maze by trial and error and then associate the positive outcome--exiting the maze--with the actions that led up to it. This lets a machine learn without instruction or even explicit examples. The idea has been around for decades, but combining it with large (or deep) neural networks provides the power needed to make it work on really complex problems (like the game of Go). Through relentless experimentation, as well as analysis of previous games, AlphaGo figured out for itself how to play the game at an expert level.
