This Person Does Not Exist is a tool that uses a generative adversarial network (GAN) to generate realistic human images. Developed by Tero Karras, et al. and Nvidia, this tool uses StyleGAN2, a type of GAN that combines traditional convolutional neural networks and generative networks. Code is available to train your own GAN and the tool can generate realistic human images, cats, horses, and chemicals. Additionally, the tool can be used to dream up any image. This tool is useful for creating realistic images for research, art, and other applications.
