Enhancing LLM Reliability: Detecting Confabulations with Semantic Entropy

**Enhancing LLM Reliability: Detecting Confabulations with Semantic Entropy** Practical Solutions and Value Highlights: We've developed a statistical method to detect errors in Language Model Models (LLMs) called "confabulations," which are arbitrary and incorrect responses. This method uses entropy-based uncertainty estimators to assess the uncertainty in generated answers, improving LLM reliability by signaling when extra caution is needed. Our method works by clustering similar answers based on their meaning and measuring the entropy within these clusters to detect semantic inconsistencies and unreliable answers. This is a critical advancement in ensuring the reliability of LLMs, especially in free-form text generation where traditional supervised learning methods fall short. We leverage semantic entropy to identify when a model's answers are likely arbitrary, helping predict model accuracy and improving reliability by flagging uncertain answers. This approach provides a robust mechanism for identifying confabulations, even in distribution shifts between training and deployment. Our study also extends the application of semantic entropy to longer text passages, demonstrating its effectiveness in detecting confabulations in extended text and offering a promising direction for improving the reliability of LLM outputs in complex and open-ended tasks.
