None of these faces are real , these all are generated by Nvidia's Artificial Neural Network.
Not only humans but also animals are rendered by this.
If i explain it in layman's terms, this Artificial Neural network is a computation model which is inspired by neurons network present in our brains, which results in pretty high accuracy in output data.
This neural network is also used in fields where accuracy is the top priority like speech recognition,language translation and objects detection.
One of the most intelligent AI work.
