摘要:
了解模型能否泛化到“野外”数据对安全部署至关重要。为此,我们研究了考虑完整预测分布的模型分歧概念——具体而言是基于Hellinger距离、Jensen-Shannon散度和Kullback-Leibler散度的分歧。我们发现,与基于top-1的对应方法相比,基于散度的分数在分布外数据上能提供更优的测试误差估计和检测率。实验涉及标准视觉模型和基础模型。
英文摘要:
Knowing if a model will generalize to data 'in the wild' is crucial for safe deployment. To this end, we study model disagreement notions that consider the full predictive distribution - specifically disagreement based on Hellinger distance, Jensen-Shannon and Kullback-Leibler divergence. We find that divergence-based scores provide better test error estimates and detection rates on out-of-distribution data compared to their top-1 counterparts. Experiments involve standard vision and foundation models.
