Scientists decode how the human brain recognises faces

MIT researchers have developed a new computational model of the human brain’s face-recognition mechanism that seems to capture aspects of human neurology that previous models have missed. The researchers designed a machine-learning system that implemented their model, and they trained it to recognise particular faces by feeding it a battery of sample images. They found that the trained system included an intermediate processing step that represented a face’s degree of rotation – for example 45 degrees from centre, but not the direction – left or right. This property was not built into the system; it emerged spontaneously from the training process. However, it duplicates an experimentally observed feature of the primate face-processing mechanism. The researchers consider this an indication that their system and the brain are doing something similar. “This…
