Overcoming the Hallucinations of AI Systems

As AI systems like ChatGPT continue to advance, one of the major challenges they face is the problem of “hallucinations” - producing confidently stated but entirely fictional information. This issue has proven difficult to overcome, as the systems are designed to produce language rather than facts. However, scientists may have found a way to help overcome this problem.

A new tool has been developed that allows AI systems to detect when they are “hallucinating” or making up facts. This is a crucial step in making AI systems more reliable and trustworthy. The tool works by using another AI system to check the work of the original one, and then another to evaluate that work. This process helps to identify when the system is producing inaccurate or arbitrary text.

The system focuses on the meanings behind the words, rather than the words themselves. It does this by feeding the outputs of the system into another system that works out whether the statements imply each other, essentially looking for paraphrases. These paraphrases can then be used to understand how likely the original system’s output is to be reliable.

“Researchers will need to grapple with the issue of whether this approach is truly controlling the output of LLMs, or inadvertently fuelling the fire by layering multiple systems that are prone to hallucinations and unpredictable errors.” - Karin Verspoor, University of Melbourne

The potential benefits of this system are significant. If AI systems can be made more reliable, they could be used in a much broader range of applications, and in more important settings. However, there are also potential dangers to consider. As we move forward with using AI systems, we will need to be careful not to inadvertently create more problems.

AI systems like ChatGPT are prone to “hallucinations”

The new method has been described in a paper titled “Detecting hallucinations in large language models using semantic entropy”, published in Nature. It is a promising development in the ongoing quest to make AI systems more reliable and trustworthy.

AI hallucinations can be difficult to detect

As we continue to develop and refine AI systems, it is crucial that we prioritize their reliability and trustworthiness. By overcoming the problem of hallucinations, we can unlock the full potential of AI and use it to make a positive impact on the world.

The future of AI is bright, but only if we can overcome its limitations
