Artificial intelligence system can tell if you're gay

A computer program can tell if someone is gay or not with a high level of accuracy by looking at a photograph, a study claims. But critics say that the software could be used to'out' men and women currently in the closet. To'train' their computer, the researchers downloaded 130,741 different images of 36,630 individual men's faces, and 170,360 images of 38,593 women from a US dating website. The users had all declared their sexuality on their profiles. Removing images which were not clear enough, they were left with even numbers of 35,326 pictures of 14,776 people, gay and straight, male and female.
