Anyone who's watched a political debate has probably wished they could influence the words coming out of a candidate's mouth. Now, machine learning is making that possible -- at least to some extent.

Researchers at the University of Washington have found a way to create fully interactive, 3D digital personas from photos albums and videos of famous people such as Tom Hanks, Barrack Obama, Hillary Clinton and George W. Bush. Equipped with those 3D models, they could then impose another person's voice, expressions and sentiments on them, essentially rendering the models as 3D digital puppets.
