English(EN) When Do Internal Probes Beat Reading the Answer? Miscalibrated Readouts and Behavior-Concealed Knowledge in Language Models

语言模型因输出校准失误而隐藏知识

一篇新的研究论文探讨了语言模型内部所知与其通过输出来表达的内容之间的差异。研究发现,虽然对模型内部状态进行线性探测可以准确预测模型的知识,但由于决策阈值校准失误,模型的实际行为往往无法反映这些知识。这个问题,特别是单一标量偏移,即使在模型的内部表示准确的情况下,也可能抹去正确的答案。研究表明,通过调整决策阈值或使用校准边际解码等简单修正,可以在不重新训练的情况下显著提高模型的行为准确性。 AI

影响 强调了大型语言模型可解释性中的一个关键差距,并提出了提高模型可靠性以及使内部知识与外部行为保持一致的方法。

    内部探测何时优于直接读取答案?语言模型中的校准失准读数与行为隐藏知识

    arXiv:2609.04582v1 Announce Type: cross Abstract: A 0.6B language model, asked to verify 1,200 logical conclusions (half valid, half corrupted by a single semantic edit), answers YES every time. Judged by behavior it discriminates nothing; linear probes on its hidden states read …
