English(EN) Does Marginal Coverage Guarantee Class-Conditional Safety for Zero-Shot VLMs Under Shift?

研究发现,分裂保角预测在分布偏移下对视觉语言模型未能实现类别条件安全

一篇新论文研究了分裂保角预测作为零样本视觉语言模型(VLMs)在数据分布偏移条件下的安全层有效性。研究发现,尽管边际覆盖率可以保持较高水平,但类别条件覆盖率会显著下降,某些类别的覆盖率甚至在整体覆盖率约为86%时接近于零。测试了各种校准技术,其中目标侧类别校准显示出最大潜力,但需要大量的标记数据。研究得出结论,边际保角覆盖率应被视为平均可靠性指标,而不是特定类别的确定性安全保证。 AI

影响 强调了当前视觉语言模型校准方法中潜在的安全差距,表明需要更强的类别条件安全保证。

    边际覆盖是否能保证零样本VLMs在分布偏移下的类别条件安全性?

    Split-conformal prediction provides marginal coverage under exchangeability and is increasingly used as an abstention layer for zero-shot vision-language models (VLMs). We audit this practice under deployment shift for CLIP, OpenCLIP, and SigLIP across ImageNet and non-ImageNet s…
