The Role of Ambiguity in Error Prediction via Uncertainty Quantification
Researchers have developed a new method to improve error prediction in Large Language Models by distinguishing between inherent input ambiguity and model uncertainty. Their approach, tested on question-answering tasks, showed that existing uncertainty quantification metrics are less effective on ambiguous inputs. By incorporating ambiguity labels, the method enhanced error prediction scores by over 10 points of PRR across various models and datasets. AI
