StyleGAN is a novel generative adversarial network (GAN)
Nvidia researchers distributed a preprint with accompanying software introducing StyleGAN, a GAN for producing an unlimited number of (often convincing) portraits of fake human faces.
This Person Does Not Exist, which displayed a new face on each web page reload.
Given that humans are evolved to specifically understand human faces, that nevertheless StyleGAN can competitively "pick apart all the relevant features (of human faces) and recompose them in a way that's coherent.
This Person Does Not Exist uses AI to generate people who look 100% real but are 100% AI-generated. This can come in handy when you need headshots for mockups or other uses. Keep refreshing.
