为什么概率性临床模型无法在不同站点间迁移?

Why Do Probabilistic Clinical Models Fail To Transport Between Sites?

Vanderbilt University Medical Center(范德堡大学医学中心)

Thomas A. Lasko, Eric V. Strobl, William W. Stead

AI总结:

本文探讨了概率性临床模型跨站点迁移失败的原因,区分了实验者可控与数据生成过程固有的来源,并提出分离站点特定实践印记与疾病因果模式的潜在解决方案。

摘要:

人工智能在医疗保健领域的日益普及,凸显了一个问题:一个在其训练站点达到超人临床性能的计算模型,在新站点可能表现显著变差。在这篇观点文章中,我们提出了导致这种迁移失败的常见来源,并将其分为实验者可控的来源和临床数据生成过程固有的来源。在固有来源中,我们更深入地探讨了可能影响数据分布的特定站点临床实践,并提出了一种潜在解决方案,旨在将这些实践在数据上留下的印记与疾病因果模式(即概率性临床模型的通常目标)分离开来。

英文摘要:

The rising popularity of artificial intelligence in healthcare is highlighting the problem that a computational model achieving super-human clinical performance at its training sites may perform substantially worse at new sites. In this perspective, we present common sources for this failure to transport, which we divide into sources under the control of the experimenter and sources inherent to the clinical data-generating process. Of the inherent sources we look a little deeper into site-specific clinical practices that can affect the data distribution, and propose a potential solution intended to isolate the imprint of those practices on the data from the patterns of disease cause and effect that are the usual target of probabilistic clinical models.
