Clustered Self-Assessment: A Simple yet Effective Method for Uncertainty Quantification in Large Language Models
arXiv:2606.03846v1 Announce Type: new Abstract: Large language models (LLMs) demonstrate remarkable performance across diverse tasks, but they often generate responses that appear plausible while being factually incorrect. This problem is compounded by the lack of explicit uncertainty estimates, which makes it difficult for users to judge the reliability of model outputs. Existing uncertainty quantification methods typically rely on indirect signals, such as entropy across sampled generations. These signals can be difficult to interpret and do not fully leverage the model's ability to assess i
The rapid advancement and widespread deployment of large language models are exposing critical limitations in their reliability and trustworthiness, making uncertainty quantification an immediate and pressing challenge.
This development addresses a core weakness of current AI, improving model trustworthiness and enabling more reliable integration into sensitive applications where accuracy and explainability are paramount.
The ability to provide better uncertainty estimates will lead to more robust and accountable AI systems, shifting perception and adoption patterns for LLMs in critical real-world use cases.
