Well, this is horrifying. Thank you. Now everyone that has one photo of me to match against now has several of them.

The article doesn't point this out, but in GANs, the parameters actually move on a continuous range. In other words, they don't just have several of your pictures, they've got all sorts of movies : A movie where your face starts out "neutral" and becomes angry. A movie where you start out angry, go to surprised and end happy. And so on. Excellent progress, I must say.

> they've got all sorts of movies

Here it is: one glorious hour of walk through the latent space of faces. You can "feel" the geometry of the latent space and its meanderings. https://www.youtube.com/watch?v=36lE9tV9vm0

In the examples, the source images are very very uniform (Caucasian, young, healthy). Does this work with other images? Can it age photos of people who are already over 50 for example? Or non-whites? Or children? Etc.

I'd like to see it applied to completely different things, what does it do to animals, a grid, a brick wall, a car, etc.

Is a trained model available anywhere?

I think this (or something like this) can be used as a way to transmit a video chat on a very low bandwidth (think tens of bytes/second) level.

You're talking about an animated avatar that just happens to be of an actual person? And only in 2D?

Is it possible to download a pre-trained model?

Yes. There are many pre-trained model. You can then use transfer learning to build on a pre-trained model to benefit from the existing computational effort.

Where are the pre-trained models?

I wish researchers showed a random mix of results, not just their best results ...

For a start, yes. A proof of pricinple would be nice. Would probably look very shitty, but would use very little bandwidth.

I read about a fictional system like this in "A fire upon the deep" by Vernor Vinge a long time ago but never thought it would be feasible. There a scene of an entire room of people interacting was being deconstructed/reconstructed for a video chat using low bandwidth.
