Now Facebook says its developed a technology for verifying whether two people in side-by-side photos are the same that comes pretty close to replicating human abilities. That project is called DeepFace, and according to Facebook its 97.25 percent accurate, which is just shy the 97.5 percent humans have scored in the same standardized test. In order to pull off that feat, the technology maps out 3D facial features, then makes a flat model thats filtered by color to characterize specific facial elements. Facebook also says its tapped into a pool of 4.4 million labeled faces from 4,030 different people on its network in order to help the system learn.
