English(EN) Subjective Risk Decomposition: A New View for Uncertainty Quantification

新不确定性量化框架源于主观风险分解

研究人员通过提出一种新观点,即不确定性度量并非基础性的,而是源于更高级别的建模决策,从而引入了不确定性量化(UQ)的新视角。该框架展示了如何通过分解主观风险,并使用严格的 Proper Loss 函数来获得认知不确定性和偶然不确定性。该方法在共同的理论基础上统一了各种 UQ 度量,并根据特定的建模场景和损失函数提出了实用的 UQ 方法。此外,该研究将此观点扩展到学习理论,分析了超额风险、近似误差和估计误差的主观风险类似物,并将它们与 UQ 联系起来。 AI

影响 这项研究为不确定性量化方法提供了统一的理论基础,有望带来更鲁棒的 AI 模型。
