新方法使用概率电路改进分布外检测

研究人员开发了一种使用概率电路(PCs)检测分布外(OOD)数据的新方法。这种方法被称为分层似然向量(HLV)和分层似然距离(HLD),它利用PCs的内部分层结构,而不仅仅是根似然。HLD度量通过检查其HLVs的期望来比较概率分布,提供了一种积分概率度量。这种方法允许训练好的PC本身代表分布内数据,消除了部署期间对预留数据的需求,并能够精确计算OOD检测度量。 AI

影响 增强了AI模型识别不熟悉或异常数据的能力,这对于在现实世界场景中稳健部署至关重要。

    一种概率电路诱导的伪度量用于分布外检测

    arXiv:2608.09117v1 Announce Type: new Abstract: Probabilistic Circuits (PCs) are tractable generative models whose internal nodes encode a hierarchy of probabilistic sum- maries over different variable scopes. Existing PC-based out- of-distribution (OOD) detection methods ignore …
