This bot's sample is a dating website. I'm going to bet my socks on the fact that all it does is detect fashion styles and trends and associate them to groups.

This bot's sample is a dating website. I'm going to bet my socks on the fact that all it does is detect fashion styles and trends and associate them to groups. The "male homosexual" group is most likely filled with individuals dressed in a more fashinable style who are also well groomed (eyebrows, etc.) I am certain that you could introduce a lot of errors by adding a bunch of metrosexual but straight individuals into the mix.

The paper states that they used an existing net, VGG-Face, to exact facial features: https://osf.io/fk3xr/ https://osf.io/fk3xr/ (page 13) >VGG-Face aims at representing a given face as a vector of scores that are as unaffected as possible by facial expression, background, lighting, head orientation, image properties such as brightness or contrast, and other factors that can vary across different images of the same person. All the heavy lifting for this paper was done by logistic regression on the facial features reported by VGG-Face, they didn't train a DNN specifically for identifying sexuality from image pixel values. The algo wouldn't have seen clothing at all.

  Thank you for the link. My respect for the researchers has increased. I still think that while the results are accurate(ish), they reveal fashion trends and not genetic changes. Can in point, the composite average of homosexual male has glasses. Facial features of homosexual are often gender atypical but that's trough a lot of effort to conform with fashion trends (eyebrow reshaping, smoother skin, "kinkier" smile, etc.). This is especially true on dating sites. The whole nature vs nurture thing. While I agree that hormone levels can impact facial features, I have yet to see a strong study proving that hormones levels can be directly linked to sexual orientation or gender identity.
