Researchers develop algorithm that uses computer vision to
identify social groups
Are you a hipster, surfer or biker? What is your urban
tribe? Your computer may soon be able to tell. Computer scientists at the
University of California, San Diego, are developing an algorithm that uses
group pictures to determine to which of these groups, or urban tribes, you
belong. So far, the algorithm is 48 percent accurate on average. That’s better
than chance--which gets answers right only nine percent of the time--but
researchers would like the algorithm perform at least as well as humans would.
