Algorithm knows you're drunk just by looking at you


Researchers at Greece's University of Patras built an algorithm that can determine with 90 percent accuracy whether a person is drunk or not based on an infrared image of his or her face.

The neural network's biggest clue is the temperature of the subject's forehead, and it doesn't need to see you sober to make the call. The image above right is the subject when drunk.
