Facebook has an autonomous facial recognition system called "DeepFace"
It currently "knows" 800 million people.
DeepFace is autonomous, it makes decisions based on cognitive capabilities it built on its own.
If I take a picture of you, and you are one of the people DeepFace already knows, it can identify you in five seconds.
It can do this at a level of accuracy as good as human beings ~97%.
DeepFace can run on the processor in a cell phone.
