Detecting critical treatment effect bias in small subgroups

no code implementations29 Apr 2024 Piersilvio De Bartolomeis, Javier Abad, Konstantin Donhauser, Fanny Yang

Randomized trials are considered the gold standard for making informed decisions in medicine, yet they often lack generalizability to the patient populations in clinical practice.

Privacy-preserving data release leveraging optimal transport and particle gradient descent

1 code implementation31 Jan 2024 Konstantin Donhauser, Javier Abad, Neha Hulkund, Fanny Yang

We present a novel approach for differentially private data synthesis of protected tabular datasets, a relevant task in highly sensitive domains such as healthcare and government.

Hidden yet quantifiable: A lower bound for confounding strength using randomized trials

1 code implementation6 Dec 2023 Piersilvio De Bartolomeis, Javier Abad, Konstantin Donhauser, Fanny Yang

Further, we show how our lower bound can correctly identify the absence and presence of unobserved confounding in a real-world setting.

Approximating Full Conformal Prediction at Scale via Influence Functions

1 code implementation2 Feb 2022 Javier Abad, Umang Bhatt, Adrian Weller, Giovanni Cherubin

We prove that our method is a consistent approximation of full CP, and empirically show that the approximation error becomes smaller as the training set increases; e. g., for $10^{3}$ training points the two methods output p-values that are $<10^{-3}$ apart: a negligible error for any practical application.
