An Empirical Framework for Domain Generalization in Clinical Settings

2021 · arXiv (Cornell University)

Clinical machine learning models experience significantly degraded performance in datasets not seen during training, e.g., new hospitals or populations. Recent developments in domain generalization offer a promising solution to this problem by creating models that …

Spatio-Temporal Hierarchical Causal Models

2025 · arXiv (Cornell University)

The abundance of fine-grained spatio-temporal data, such as traffic sensor networks, offers vast opportunities for scientific discovery. However, inferring causal relationships from such observational data remains challenging, particularly due to unobserved confounders that are specific …
