  • Facebook's researchers have built DeepFace, an algorithm that can pick a face out of a crowd with 97.25% accuracy. The trouble with most face recognition systems is that if the faces are slightly off-center in the photo the software will struggle to find a match. Yaniv Taigman and colleagues at Facebook's AI lab found a way round this problem. They created a 3D model of a face from a photo that can be rotated into the best position for the algorithm to start matching. They then used a neural network that had been trained on a massive database of faces to try and match the face with one in a test dataset.
