EP254: Why Innovation Guarantees AI Hallucination

Title: Innovation: An Almost Characterization of HallucinationSource: http://arxiv.org/abs/2605.26808v1Summary:This work establishes a foundational probabilistic framework that formalizes hallucination as "innovation," providing a mathematical characterization of why LLMs produce outputs outside their training data. By deriving new lower bounds on hallucination rates based on "missing mass," it offers a critical theoretical breakthrough for understanding and mitigating the core reliability limits of generative models.
