When you visit "This Person Does Not Exist" (this person does not exist) website, you'll see a smile at you in the face (each refresh will jump out of a different color face). Despite these very real smile, it is difficult to distinguish the human eye, but these smiling faces generated by the neural network algorithm, are not the real life of a real person.
The site's creator Phillip Wang released on February 12 in the Facebook group in this site, claiming that the site of the neural network algorithm can be divided facial image from a 512-dimensional vector. The technology is based on the most advanced artificial intelligence StyleGAN NVIDIA design of a neural network can be isolated and used to image various elements of learning and generate a new image. Nvidia engineers updated on February 6 on the arXiv pre-print a paper described in detail.
StyleGAN is NVIDIA released the latest research results by the end of 2018, the official open source code, you need Python 3.6 and TensorFlow 1.10 or more (support GPU). And released with the official code implementation, as well as Flickr HD face data sets. Dataset contains 70000 1024 × 1024 high-definition portrait. Nvidia said that these photos on age, race, and background images, has a very strong diversity.
