The system can also generate realistic images of horses, buses, bicycles, plants and many other common objects. Today, many systems generate images and sounds using a complex algorithm called a neural network. As it built a system that generates new celebrity faces, the Nvidia team went a step further in an effort to make them far more believable. “The computer learns to generate these images by playing a cat-and-mouse game against itself,” said Mr. Lehtinen. With their method, called progressive GANs, the Nvidia researchers built a system that begins with low-resolution images and then gradually progresses to higher resolutions.
