Artificial Intelligence: Machine learns playing video games

Google has developed a machine that can learn to play and win computer games.

The machine played better than a professional human in more than half of the 49 Atari games it played.

Dr Demis Hassabis, Google DeepMind's vice president of engineering, said: "Up until now, self-learning systems have only been used for relatively simple problems.

"For the first time, we have used it in a perceptually rich environment to complete tasks that are very challenging to humans."
