Hallucination is a word that is being increasingly used to describe the tendency of artificial intelligence, or AI, technology to produce false or contradictory information. In response to the problem, some researchers say generative AI tools must be paired with fact-checking systems so that AI chatbots are supervised and any inaccuracies they generate can be readily revealed. The potential solution presents a formidable challenge, says artificial intelligence researcher Subbarao Kambhampati, a professor in the School of Computing and Augmented Intelligence, part of the Fulton Schools, because there is yet no reliable way to always assure the accuracy of computer generated material.
