How an AI 'cat-and-Mouse Game' Generates Believable Fake Photos

Researchers at NVIDIA say they have developed an artificial intelligence (AI) system that analyzes thousands of celebrity photos, infers common patterns, and generates new images that are closely similar.

They note the underlying idea of the project is to expedite and enhance the creation of computer interfaces, games, and other media, eventually enabling software to rapidly generate realistic imagery.

The engineers set up two generative adversarial networks--one to produce the images and another to ascertain the images' authenticity.

"The computer learns to generate these images by playing a cat-and-mouse game against itself," says NVIDIA's Jaakko Lehtinen.

However, Tim Hwang with the Ethics and Governance of Artificial Intelligence Fund sees a negative aspect to this form of technological progress. "The concern is that these techniques will rise to the point where it becomes very difficult to discern truth from falsity," he warns. "You might believe that accelerates problems we already have."
