New method improves LLM uncertainty quantification for question answering

Researchers have developed a new method called Neighborhood Elites (NE) to improve uncertainty quantification in question-answering large language models. This technique aims to identify when LLMs produce incorrect answers that are indistinguishable from correct ones. NE achieves this by systematically generating diverse input rewrites that preserve the answer while controlling for the type of edit and the explicitness of the answer's support within the context. Experiments across multiple QA datasets and LLMs show that NE significantly enhances failure detection compared to other methods. AI

IMPACT Enhances reliability of LLM question-answering systems by improving failure detection.

    Neighborhood Elites: Quality-Diversity Search for Uncertainty Quantification in Question Answering

    arXiv:2610.40278v1 Announce Type: new Abstract: Large language models (LLMs) are increasingly capable, yet they produce wrong answers indistinguishable from correct ones. In question answering (QA), such an error propagates unnoticed into downstream tasks. Perturbation-based unce…
