From a raise of an eyebrow to a tilt of the head, we use several micro-movements when we’re lying without even knowing it. Now, scientists have developed an artificial intelligence system that can detect these micro-expressions and detect if you’re lying – and it’s already ‘significantly better’ than humans. The researchers hope their system could soon be used in courtrooms to tell if people on the stand are telling the truth.
The AI system, called Deception Analysis and Reasoning Engine (DARE), has been developed by researchers from the University of Maryland and Dartmouth College. To develop DARE, the researchers trained the system using videos of people in the courtroom. In their study, published in arXiv, the researchers, led by Dr. Zhe Wu, said: ‘On the vision side, our system uses classifiers trained on low-level video features which predict human micro-expressions.’ READ MORE
