A new machine learning paper shows how AI can take footage of someone and duplicate the video with the subject looking an age the researchers specify. The team behind the paper, from the University of Arkansas, Clemson University, Carnegie Mellon University, and Concordia University in Canada, claim that this is one of the first methods to use AI to tackle aging in videos. The system was trained on an expanded dataset of photos of showing individuals at different ages. Reinforcement learning, a technique that rewards an AI model for getting a task correct, comes into play by rewarding the system when the synthesized features, like wrinkles, appear similarly across consecutive video frames. Similar approaches power the “deepfake” technology that has raised alarms about the prospect of AI-powered video propaganda.
