AI Can Detect Sexual Orientation Based On Person's Photo (cnbc.com)
ugen shares a report from CNBC: Artificial Intelligence (AI) can now accurately identify a person's sexual orientation by analyzing photos of their face, according to new research. The Stanford University study, which is set to be published in the Journal of Personality and Social Psychology and was first reported in The Economist, found that machines had a far superior "gaydar" when compared to humans. Slashdot reader randomlygeneratename adds: Researchers built classifiers trained on photos from dating websites to predict the sexual orientation of users. The best classifier used logistic regression over features extracted from a VGG-Face conv-net. The latter was done to prevent overfitting to background, non-facial information. Classical facial feature extraction also worked with a slight drop in accuracy. From multiple photos, they achieved an accuracy of 91% for men and 83% for women (and 81% / 71% for a single photo). Humans were only able to get 61% and 54%, respectively. One caveat is the paper mentions it only used Caucasian faces. The paper went on to discuss how this capability can be an invasion of privacy, and conjectured that other types of personal information might be detectable from photos. The source paper can be found here.
Maybe they're getting interference from a gay weather balloon.

It might have the opposite effect. It is easy to hate a faceless "other". It is harder to be homophobic when you know your friends and relatives are gay.
One of the reasons that gay acceptance happened so fast is positive feedback. As gays felt more comfortable "coming out", more people realized that "normal" people they knew were gay, leading to even wider acceptance.
Wait, is the Pacific Northwest homophobic? I have some friends that live up in Oregon and they're extremely gay and I never heard them complain about the region being particularly difficult for them. One just sent me a photo taken from his backyard of a mountain being consumed by fire. I'm pretty sure he had nothing to do with that, though, despite the fact that he's flaming.
(I used this joke with him, too, and he didn't seem to mind. He would have told me if it had offended him.)
You are welcome on my lawn.
I would LOVE to get a copy of this program and, not only try it out on myself and my friends, (I think we're relatively secure in our sexuality) but try it on famous people.
Specifically: Republican lawmakers and perhaps even Christian preachers! (How about Mr. Macho himself, Putin?)
I really, really know I'm going to be down-modded for this but please hear me out. Haven't you wondered why those people who are so against homosexuality often turn out to be gay themselves? (Dennis Hastert and that lawmaker caught in the men's restroom soliciting a cop come to mind). Maybe it's because they are so ashamed that the only way they can bury their feelings is to actively suppress it. That's fine if you don't want to face the truth but the problem is being lawmakers, representatives of God, they infringe on many, many other peoples lives. So let's drag them out of the closet and into the photo booth! (Actually I don't think that'll be necessary, from what little I've read about this algorithm it doesn't require any particular lighting or "orientation" (ha ha) for the photo so many of the pictures of these famous people should be just fine.)
On a more serious note: This is just the latest in a trend of events which a friend of mine has said is "the end of privacy". With technologies like these (soon I'm sure they'll be able to analyze videos to see, by looking at imperceptible* subtle face color flushing and breathing patterns, who is attracted to whom), social media and the hack of personal databases like Equifax, NOTHING will be able to be kept secret. I wouldn't doubt that the CIA is already using some of this stuff to determine, remotely, if someone is lying on camera when they say something. It will be hard to legislature laws to keep it out of business and impossible to keep out of statecraft.

If the AI were to simply assign scores of "Straight" to EVERYONE, it would achieve 90% accuracy for men and 85% accuracy for women, since about 90% of men are straight and about 85% of women are straight. So scores of 91% and 85% accuracy are not statistically significant.
The algorithm was trained on pictures from dating sites, which isn't exactly a representative data set. A large portion of the pictures have been manipulated or at least carefully selected by the person who uploaded them. There are a portion of gays who try to signal their gayness through things like styling and mannerisms, which would be easy for an algorithm to pick up on. These types are going to be overrepresented in the data set.
