Why AI Researchers Like Video Games

Games help them understand reality.

Last year Artur Filipowicz, a computer scientist at Princeton University, had a stop-sign problem. Dr Filipowicz is teaching cars how to see and interpret the world, with a view to them being able to drive themselves around unaided. One quality they will need is an ability to recognise stop signs. To that end, he was trying to train an appropriate algorithm. Such training meant showing this algorithm (or, rather, the computer running it) lots of pictures of lots of stop signs in lots of different circumstances.
