Roland Piquepaille writes: "Researchers at University College London (UCL) have written a computer program using neural networks which are duped by optical illusions the same way as we do. Their virtual robots, which were trained to 'see' like us, could help to understand why we fall for optical illusions. This might also be important for robot vision. If robots are trained to 'see' like us, they will act like us — and make mistakes. Very interesting... But read more for additional references and one of the visual illusions featured on the Web site of the lead researcher for this project."
