Two new research papers explore methods for understanding and quantifying uncertainty in large language models (LLMs). The first paper proposes a framework to decompose LLM uncertainty into input ambiguity, knowledge gaps, and decoding randomness, offering insights into model reliability and hallucination detection. The second paper introduces an approach using evidential knowledge distillation to enable efficient uncertainty estimation without the computational cost of traditional sampling methods, achieving comparable performance with a single forward pass.
