Hi, I'm Rasmus and worked on the algorithms behind faces.ethz.ch. If you have any technical questions, let me know! Sorry for having some stability issues, we got much more traffic than expected and are currently working hard to fix everything!

Hi Rasmus,

Cool work! I'm curious regarding the training dataset. What is the distribution of faces by race/age? Also regarding the raters, what is their distribution? (Race/age/cultural background)?

It's widely known that attractiveness is heavily dependent on cultural upbringing.

Signed, Butthurt dev whose best pic only rated an "OK".

EDIT: You also rated Yoona (a Korean pop star) as just "Nice": http://imgur.com/uJVnQ9S. I guess that makes me feel better about my "OK". I'd stay out of Korea if I were you---I hear their fans aren't very forgiving.

Hi fatjokes,

I am Radu, one of the authors.

As mentioned in our article (http://arxiv.org/abs/1510.07867v1), the training dataset for attractiveness is from Blinq. The underage and above 37 years old face images were discarded. All people are heterosexual in our training dataset and mainly from Zurich area, Switzerland. Therefore, our model of attractiveness fits the cultural bias of Zurich, Switzerland.

We consider faces.ethz.ch a little fun tool. I hope that the fans of Yoona will understand :) With more training data from abroad Switzerland our algorithms will fit their expectations.

For age and gender we used much more and diverse data, therefore are more reliable for the majority of ethnic backgrounds.

From a data privacy point of view I would very much appreciate if you added a prominent "delete upload" button to the result page.

[Jach]

"We do not save the uploaded image." from the take-this-seriously? popup.

[rndmind]

Yes a "delete" button would nice.

[rrothe]

We do not store any photo on the server, so no worries!

[tlrobinson]

Well, you could still add a delete button to make people feel better (I'm only half joking)

[TeMPOraL]

And as a potential user I'm only half-insulted.

But seriously, what purpose would it serve over a promise in TOS? A normal user will trust both (except the button would be bullshitting them). A privacy-obsessed one will trust neither.

[jmorrow977]

You could make a delete button which merely opens a popup to explain that they do not save it in the first place. That way if they're looking for a delete button, they'll find it, but it will give them the right information.

Could this site be used to optimize your dating profile photo (if you have one)? I'm probably "Hmmm" on most photos but possibly "Ok" or even "Nice" on a few. What does the algorithm want?

[timofter]

Yes, it is a foreseen application.

Your website is offline, do you have a paper about your technology?

[mkuhn]

It is back right now and they list the research.

[MrQuincle]

Hi Rasmus, you described your paper on age estimation on the site. Do you also have something written on the hotness scale? :-)

Edit: Sorry, missed it! http://arxiv.org/pdf/1510.07867v1.pdf

[Madmallard]

None of the images I am uploading are working. It is saying it cannot detect a face on any of them. Is this a masking of the stability error or some other issue?

[otakucode]

It is trying to let you know that you are not quite human.

[anotheryou]

What does it analyze?

Picture or Extracted Face?
