New SkewD Algorithm Enhances Causal Discovery Robustness in Noisy Models

研究人员开发了 SkewD,这是一种用于位置-尺度噪声模型(LSNM)中因果发现的新算法,该算法对偏斜噪声分布具有鲁棒性。传统方法通常假设噪声是对称的,例如正态分布,当噪声偏斜时(在真实世界数据中很常见),这可能导致不可靠的推断。SkewD 扩展了现有框架以处理偏斜正态设置,采用启发式搜索和期望条件最大化算法相结合的方式进行参数估计。在合成数据集和基准数据集上的实验评估表明,SkewD 表现出色,并且即使在高偏斜度下也能保持鲁棒性。 AI

影响 提高了在具有非理想噪声分布的复杂真实世界数据集中的因果发现的可靠性。

    位置-尺度噪声模型中的偏度鲁棒因果发现

    arXiv:2511.14441v2 Announce Type: replace Abstract: To distinguish Markov equivalent graphs in causal discovery, it is necessary to restrict the structural causal model. Crucially, we need to be able to distinguish cause $X$ from effect $Y$ in bivariate models, that is, distingui…
