Researchers have developed a theoretical framework to understand and quantify "hallucinations" in AI models used for inverse problems, such as medical imaging. The study shows that these realistic but incorrect details can stem from the inherent ill-posed nature of the problem itself, not just specific models. The new approach provides computable bounds on hallucination magnitudes and algorithms to assess reconstruction faithfulness, demonstrating broad applicability across various imaging tasks and modern generative models.
