The latest research out of Facebook sets machine learning models to tasks that, to us, seem rather ordinary — but for a computer are still monstrously difficult. These projects aim to anonymize faces, improvise hand movements and — perhaps hardest of all — give credible fashion advice. The research here was presented recently at the International Conference on Computer Vision, among a few dozen other papers from the company, which has invested heavily in AI research, computer vision in particular. Modifying faces in motion is something we’ve all come to associate with “deepfakes” and other nefarious applications.
