新理论将马氏余弦相似度与探针性能联系起来

研究人员在理论和实践上都证明了马氏余弦相似度(MCS)是线性探针的分布外 AUROC 的有力预测指标。这种关系在各种模型、层和概念域中都成立。该研究证明,对于具有高斯投影的平衡类别,分布外 AUROC 和到参考探针的 MCS 都是探针在测试数据上信噪比的线性函数。MCS 被提出作为一种理论上合理且实践有效的替代方法,用于在可解释性研究中比较线性探针,取代欧氏余弦相似度。 AI

影响 提供了一种有理论依据的方法来评估 AI 模型的可解释性,有望增进对模型行为的理解。

    比较线性探针与马氏余弦相似度

    arXiv:2606.19603v1 Announce Type: new Abstract: Linear probes are widely used in interpretability research and often compared by cosine similarity. The Mahalanobis cosine similarity (MCS) between two directions, which reweights the inner product by test data covariance, is a natu…
