新“预测导向后验”统计原理揭晓

作者 PulseAugur 编辑部 · [1 个来源] ·

一种名为预测导向（PrO）后验的新统计原理已被引入，旨在结合参数推断和密度估计的优点。该方法基于预测能力表达不确定性，理论上收敛于预测最优模型平均，并优于经典和广义贝叶斯后验预测分布。当数据生成分布无法恢复时，PrO后验会适应模型误设，稳定地趋向于一个不可约不确定性分布，而不是单一模型。已开发出一种使用平均场Langevin动力学的采样算法来实现PrO后验，数值示例验证了其现实意义。 AI

    预测导向的后验

    arXiv:2510.01915v3 Announce Type: replace-cross Abstract: We advocate for a new statistical principle that combines the most desirable aspects of both parameter inference and density estimation. This leads us to the predictively oriented (PrO) posterior, which expresses uncertain…
