MMD-Flagger: Leveraging Maximum Mean Discrepancy to Detect Hallucinations

arXiv — cs.CL•Thursday, October 30, 2025 at 4:00:00 AM

A new method called MMD-Flagger has been introduced to tackle the challenge of detecting hallucinations in large language models (LLMs). As these models become increasingly integrated into our daily lives, ensuring the accuracy of their outputs is crucial, especially in critical applications. MMD-Flagger utilizes Maximum Mean Discrepancy to effectively identify content that may appear fluent but lacks grounding in reality. This advancement is significant as it enhances the reliability of AI-generated content, making it safer for various uses.
