Good article and great tech. However, I don't know if I believe the results are as good as they claim. Many of the pictures look a bit off to me, like they all have dead eyes. Maybe celebrities generally look like that anyway, so it is being true to form. :) In particular, I think this guy is missing a pretty significant part of his head: https://static01.nyt.com/newsgraphics/2017/12/26/ai-faces/8e...

Most likes I ever got on OKCupid was when I used a GAN-generated celebrity as my profile picture. Just one girl noticed something wasn't quite right.

Scary to think where this will be in 10 years. Perhaps even video evidence will be hard to believe any more. How do you convict someone if this technology is mature?

And or how do you prove someone's innocence if you can generate a believable, fake, crime video. Supporting counter evidence will become that much more important.

If there were a government conspiracy to put you away, most of the time, they wouldn't need fake video evidence to convict you - just a bit of prejury by officer witnesses.

The hair was the giveaway to me. I stared at the two "which one is real" images for a couple minutes thinking, "They both have that fake looking wavy hair, I thought for sure neither was real." Cheap trick NYTimes. Cheap.

look at their foreheads, there's still like blurry half-generated wavey hair texture on their skin.

I don't understand the images associated with that article. They purport to show the progressive refinement of the output over a series of days. But the figure changes dramatically from image to image, all the way to the end of the run. At the very least it seems the output is not stable: a human has to decide when to stop the Wheel of Fortune. It looks more like a series of images taken from different training sets…

I am not sure if "unstable" is the word I would use. Sure, even after training for days the GAN produces not-so-realistic images, but the rate at which it generates those images gradually decreases over the training period and the images get more "realistic".

>How do you solve the 'where to stop' problem if the output is so unstable?

Looking at the discriminator loss would be a good start for that.

Excellent images and the more I think about what this could be used for the creepier it gets. One day, truly, software will be very dangerous.

And it makes you wonder, what is the current legal framework preventing this kind of tool to be misused? How does it differ across countries/unions?

How can such a thing be enforced to begin with?

Are companies/labs/universities/individuals themselves the only thing standing between fair play and massive misuse of realistically generated media?
