Scientists develop AI that can learn which faces you find attractive directly from your brain waves

An artificial intelligence system has been developed that can delve into your mind and learn which faces and types of visage you find most attractive. Finnish researchers wanted to find out whether a computer could identify facial features we find attractive without any verbal or written input guiding it. The team strapped 30 volunteers to an electroencephalography (EEG) monitor that tracks brain waves, then showed them images of'fake' faces generated from 200,000 real images of celebrities stitched together in different ways. They didn't have to do anything - no swiping right on the ones they like - as the team could determine their'unconscious preference' through their EEG readings. They then fed that data into an AI which learnt the preferences from the brain waves and created whole new images tailored to the individual volunteer.
