There was a pic of an older guy, but what was unsettling was the woman peeking over his shoulder; like a friend or a family member, leaning into the photo. Her eyes were melting into black and white streaks curling down over her sagging cheeks; her smile was perfectly white, and just a little too long. I refreshed on instinct, and haven't seen anything like it since.

Yep, I've seen some ones like that too. The NN is quite good at knowing what people look like, but it's much worse at knowing what people tend to be next to and sometimes you get some horrors.

Earlier quoted context omitted.

But what's the incentive for doing that? What are you offering to those who work on adtech for them stop or to those who do work for $EvilCorp.

Moral decency doesn't warrant reward.

Then why should I comply with your sense of morality, if you have nothing to offer?

The background, clothing and especially other people in the image are still a dead giveaway that it's not a real person. It's kind of weird how the algorithm borks something relatively simple as the texture of clothing.

Yeah, you'd think that some GAN scheme would be able to weed that out?

I don't know but I imagine somebody might want to generate an algorithm that puts random clothes on people. There's so much money going on in the fashion industry and beautifying. If you can see how a new shirt fits on an existing person you can also fit a shirt on a fake person right?

I just realized the potential this has for ruining dating apps by filling up the majority of people on the program with fake generated people that just waste enough of the participants time that they never get anywhere.

So, the specific person may not exist, but likely someone very, very similar in appearance does. I've come across people in life that I would have sworn were twins. I'm curious how combinatorically low the number of facial features need to be before people resemble one another.

My gut reaction is that the model does an apparently credible job of simulating faces, but cannot take into consideration their underlying biology. I would think a lot of the features these non-existent people have might be biologically incompatible for reasons we don't know. Facial features are incredibly sensitive to exposure to gene:environment interactions. So, I have doubts today they look like anyone real.

Now try this: http://whichfaceisreal.com/

I got so used to checking the background first that when I saw http://whichfaceisreal.com/realimages/47361.jpeg my mind immediately told me that this one is fake.

It only took me a while to notice that this is an actual human face in the background, just photographed from a peculiar angle and bearing a peculiar expression - not a neural network artifact.

I have a question - When generating a new person (or whatever it is that does not exist) can you know that it isn’t like any of the images that went into the training data set? How likely is it for it to actually exist after all?

The model has 18x512 parameters, and all 9000 parameters are 32-bit floats. Even assuming only 16 bits of randomness for each parameter (to keep them small enough, so you don't get too wild, because the center of 0 is a pretty homogenized face), 16^9000 is a lot of permuations of faces. They will, of course, borrow from all of the 70k faces on Flickr that power StyleGAN, in varying degrees.
