Scientists Are Taking the Fight Against Deepfakes to Another Level



Imagine a flag flapping gently in the wind on a sunny day. Now think of it flapping more aggressively as the wind gets up. Our imaginations are powerful simulators. Indeed, experienced observers can get a good sense of the wind speed just be looking at flags. This ability requires a powerful mental model that can simulate the real word, and humans are well equipped to do this. We constantly use mental models to predict everything from the trajectory of a football to the necessity of carrying an umbrella. But computer models are not nearly as powerful in this respect. Computer scientists can realistically simulate the way a flag flaps using a model that includes variables such as the speed of the wind and the viscosity of air, along with the strength, weight and geometry of the flag material. The model also relies on the equations of fluid flow that describe how these parameters are linked. But show the same computer a flapping flag and it will give it a blank stare. There is no way…
