South Korean researchers have developed a new way to finally make AI models acknowledge their unfamiliarity with topics – similar to human behaviour. The breakthrough could improve the reliability of AI models used in fields like autonomous driving and medicine, researchers from the Korea Advanced Institute of Science and Technology say. Previous research has exposed AI “overconfidence” as one of the major risks in the use of such tools to make decisions, especially in fields like medical diagnosis . Commonly used AI models like OpenAI’s ChatGPT have been shown to “hallucinate”, or make up facts, as they are incentivised to make guesses rather than admit their lack of knowledge. Now, researchers have developed a method that enables AI to recognise situations with unfamiliar or unseen knowledge, helping improve the overall reliability of chatbots.…
