ThisPersonDoesNotExist.com uses AI to generate endless fake faces

The ability of AI to generate fake visuals is not yet mainstream knowledge, but a new website -- ThisPersonDoesNotExist.com -- offers a quick and persuasive education. The site is the creation of Philip Wang, a software engineer at Uber, and uses research released last year by chip designer Nvidia to create an endless stream of fake portraits. The algorithm behind it is trained on a huge dataset of real images, then uses a type of neural network known as a generative adversarial network (or GAN) to fabricate new examples. "Each time you refresh the site, the network will generate a new facial image from scratch," wrote Wang in a Facebook post. He added in a statement to Motherboard: "Most people do not understand how good AIs will be at synthesizing images in the future."
