Adaptive discovery of effect modification in matched observational studies
Yu Gui, Dylan S Small, Zhimei Ren
Understanding effect modification -- how treatment effects vary across subpopulations -- is practically important in observational studies, as it helps identify which subgroups are…
Confidence on the Focal: Conformal Prediction with Selection-Conditional Coverage
Ying Jin, Zhimei Ren
Conformal prediction builds marginally valid prediction intervals that cover the unknown outcome of a randomly drawn test point with a prescribed probability. However, in practice,…
Selection from Hierarchical Data with Conformal e-values
Yonghoon Lee, Zhimei Ren
Distribution-free predictive inference beyond the construction of prediction sets has gained a lot of interest in recent applications. One such application is the selection task, w…
Conformal Alignment: Knowing When to Trust Foundation Models with Guarantees
Yu Gui, Ying Jin, Zhimei Ren
Before deploying outputs from foundation models in high-stakes tasks, it is imperative to ensure that they align with human values. For instance, in radiology report generation, re…
