The social network announced that its analysts have developed Deepface, a new facial recognition technology that is almost as accurate as human perception. The new program, created by four artificial intelligence analysts, is accurate around 97.25 percent of the time, or almost as often as human perception, which is estimated to be around 97.5 percent accurate. Developed using a dataset of 4 million images of 4,000 faces, Deepface corrects the angle of each face analyzed before comparing it to a 3D model of the average face.
