Durchbruch: Eine künstliche intelligenz schlägt einen professionellen Go-Spieler

Der Artikel „Mastering the game of Go with deep neural networks and tree search“ der morgigen Nature-Ausgabe (28.01.2016) berichtet über den Erfolg einer beim Google DeepMind entwickelten künstlichen Intelligenz, einen professionellen Go-Spieler zu schlagen:

The game of Go has long been viewed as the most challenging of classic games for artificial intelligence owing to its enormous search space and the difficulty of evaluating board positions and moves. Here we introduce a new approach to computer Go that uses ‘value networks’ to evaluate board positions and ‘policy networks’ to select moves. These deep neural networks are trained by a novel combination of supervised learning from human expert games, and reinforcement learning from games of self-play. Without any lookahead search, the neural networks play Go at the level of state-of-the-art Monte Carlo tree search programs that simulate thousands of random games of self-play.
