English(EN) What Do Sparse Autoencoder Feature Discovery Scores Identify? From Activations to Interventions

新研究质疑稀疏自编码器特征发现方法

一篇新研究论文探讨了稀疏自编码器(SAE)特征的有效性,这些特征通常通过其激活与模型行为的相关性来识别。该研究提出使用干预归因,特别是干预对模型输出的一阶效应,作为更准确的指标。研究人员发现,观察性特征发现证据通常无法识别这种归因,并开发了一种基于梯度的方​​法来弥合这一差距。跨多个模型-SAE对的实验表明,基于梯度的预测与干预结果非常匹配,优于传统的探针式方法。 AI

影响 这项研究可能带来更准确的理解和控制大型语言模型行为的方法。

    稀疏自编码器特征发现分数识别了什么?从激活到干预

    arXiv:2610.15850v1 Announce Type: cross Abstract: Sparse autoencoder (SAE) features are typically discovered from how their activations co-vary with behaviour, yet they are often used through interventions such as steering or ablation. We take intervention attribution, the first-…
