"Here we can see that the eigenvalues vanish after 7, suggesting that the rank of the image data is 6."
Does this mean there are only 6 different faces shared among the 20 girls?
Korean Beauty Contestants – Face Morphing

#12It's all in good spirit, but I can't help to note that it wreeks of the old racist trope "all look the same" http://healthland.time.com/2010/11/24/they-all-look-the-same... And perhaps also a bit sexist? I dunno, maybe I'm overly sensitive.
When it's actually got a foundation in math, it stops being a racist trope and becomes a valid scientific inquiry. Sexist? Overly sensitive would be one word for it.
Unless the "foundation in math" is really confirmation bias, which math as used by humans is still vulnerable to.

#13When you look at them individually they don't look very similar. It's mainly the makeup that highlights the same parts of their faces so when they're flashed all together (eyes in the same spot) it wrongly appears they all look the same.
Re: Korean Beauty Contestants – Face Morphing
#14It's worrying how this keeps getting upvoted despite having been debunked before it even hit HN, and the top comments on both HN and the original post pointing to the article that debunks it. This is one scenario in which HN could really use downvotes.
For me it doesn't really make a huge difference if plastic surgery or photoshop are the culprit. So these women don't actually all look like clones, they're just presented as clones; great.

It's not a racial thing. See these translated Korean netizen comments: http://netizenbuzz.blogspot.com/2013/04/foreign-media-outlet...
> 1. [+238, -4] They look the same even in our eyes, I can't imagine in the eyes of foreigners... -,.-
> 2. [+234, -9] ㅋㅋㅋㅋ I thought all the faces were ctrl + C and ctrl + V with just the shirts changed. They should be ashamed of getting plastic surgery, how could they even think of entering a beauty contest? Seems like plastic surgeons can surgically remove shame now as well..
> 4. [+31, -1] Just turn Miss Korea into an exhibition contest for plastic surgeons
> 5. [+18, -2] I'm so embarrassed... They should make sure in the next Miss Korea that they only allow natural girls
> 10. [+17, -0] That's why they're called 'docturnal twins'. Twins made by plastic surgery doctors.

#16"Here we can see that the eigenvalues vanish after 7, suggesting that the rank of the image data is 6." Does this mean there are only 6 different faces shared among the 20 girls?
That's one way of putting it. A rank of six implies that if all of the faces were represented by a matrix (e.g. with 20 rows, one for each face), the dimensionality of the column space would be six. That is, all 20 faces could be represented by linear combinations of six orthogonal faces.
OP implies that six "eigenfaces" faces represent an eigenbasis for the space of all 20 faces (that they are eigenfaces doesn't necessary imply that they form an eigenbasis, not every vector space has sufficient geometric multiplicity to have an eigenbasis).

#17"Here we can see that the eigenvalues vanish after 7, suggesting that the rank of the image data is 6." Does this mean there are only 6 different faces shared among the 20 girls?
It means that the faces can be described using only six uncorrelated parameters. Or to put it another way, there are only six axis of variations. Each face is a combination of the six eigenfaces, but there is still an infinity of different ways to combine these faces, and so an infinity of possible faces.
(Without a comparison to the general population, it's not obvious that 6 is a small number here, so take my "only" 6 cautiously)

I think it only means that each of the 20 faces can be composed from combinations of 6 "basis" faces. I don't know how that compares to the eigenface decomposition of 20 less similar people, I would imagine it is more a byproduct of the process itself than something meaningful?

This experiment doesn't seem to be positing at all Koreans look the same but rather that all Korean beauty contestants look he same. The implication being, not that Koreans look similar to each other, but that they have similar standards of beauty. Apparently, most of these women have had plastic surgery so they all seem to have the same ideal when it comes to their face. I'd like to see a Brazilian (another country with a large plastic surgery industry) equivalent to see if it's the same.

#20Small correction: I saw this somewhere on the web yesterday, and it turns out that these are Miss Taegu contestants, not Miss Korea.
