UnverifiedDifferent uncertainty types correspond to different engineering actions: ambiguity corresponds to active clarification, missing information corresponds to triggering retrieval, conflicting evidence corresponds to labeling conflicts and arbitration, and general uncertainty serves as the fallback category.75% similarUnverifiedResearch ambiguity refers to a class of challenges where problem boundaries are unclear, data quality varies, or multiple contradictory conclusions exist.65% similarUnverifiedThe margin of error only reflects the uncertainty introduced by sampling and cannot encompass non-sampling errors, such as question wording bias, non-response bias, coverage bias, and social desirability bias.62% similarUnverifiedUsing disagreements among multiple models as an uncertainty signal is a low-cost, automatable means of quality diagnosis.62% similarUnverifiedWhen the geometry of the ambiguity set does not match the true structure of prediction errors, a very large radius is needed to cover the uncertainty, leading to overly conservative decisions.61% similar
