无监督域偏移下预测区间的最优聚合

研究问题
当源域有带标签样本、目标域只有协变量时,如何聚合预测区间,使其在目标域保持适当覆盖并尽量缩小宽度?
方法与思路
作者分别研究源域与目标域通过有界密度比或保测度变换关联的情形,提出区间聚合方法,并分析目标域覆盖与宽度。
材料陈述的贡献
摘要称,方法具有计算便利性,并提供预测区间覆盖和宽度的理论保证及有限样本界,同时通过真实数据展示应用表现。
阅读关注点
应核对两类域关联条件的具体含义、目标结局信息如何由源域转移,以及密度比或变换的获取方式和有限样本界的依赖项。
阅读边界
这是 arXiv 预印本,未核验同行评审或期刊接收;摘要未说明覆盖类型及域关联细节,不能据此认为方法适用于任意分布变化。

原文摘要

As machine learning models are increasingly deployed in dynamic environments, it becomes paramount to assess and quantify uncertainties associated with distribution shifts. A distribution shift occurs when the underlying data-generating process changes, leading to a deviation in the model's performance. The prediction interval, which captures the range of likely outcomes for a given prediction, serves as a crucial tool for characterizing uncertainties induced by their underlying distribution. In this paper, we propose methodologies for aggregating prediction intervals to obtain one with minimal width and adequate coverage on the target domain under unsupervised domain shift, under which we have labeled samples from a related source domain and unlabeled covariates from the target domain. Our analysis encompasses scenarios where the source and the target domain are related via i) a bounded density ratio, and ii) a measure-preserving transformation. Our proposed methodologies are computationally efficient and easy to implement. Beyond illustrating the performance of our method through real-world datasets, we also delve into the theoretical details. This includes establishing rigorous theoretical guarantees, coupled with finite sample bounds, regarding the coverage and width of our prediction intervals. Our approach excels in practical applications and is underpinned by a solid theoretical framework, ensuring its reliability and effectiveness across diverse contexts.
