Why Google DeepMind Is Putting AI on the Psychologist's Couch

Artificial intelligence can now carry out many of the same cognitive tasks humans can, but we still don't really understand how AIs think. Google DeepMind plans to train long-standing tests of human cognitive skills on machine minds to learn how they work. A long-standing problem in AI research has been the fact that deep neural networks are "black boxes." You can't tell how these algorithms work just by looking at their code. They teach themselves by training on data and there's no simple flow diagram a human can follow.
