When you visit the website "This Person Does Not Exist" you will likely see a face smiling back at you.

Seems innocent enough -- until you realize the face is not actually real, but generated by a neural network algorithm.

That person is not real.

The website's neural network algorithm codes a "facial image from scratch from a 512 dimensional vector", according to Phillip Wang, who created and posted about it in a Facebook group on Feb. 12.

Wang suggested he created the site to "raise awareness for what a talented group of researchers made at Nvidia over the course of 2 years," according to a post in Hacker News.

The technology is based on a state of the art Nvidia-designed AI known as StyleGAN -- a neural network that can separate aspects of an image to learn and generate new images.
