Causal Fairness under Unobserved Confounding: A Neural Sensitivity Framework

no code implementations30 Nov 2023 Maresa Schröder, Dennis Frauen, Stefan Feuerriegel

This enables practitioners to examine the sensitivity of their machine learning models to unobserved confounding in fairness-critical applications.

A Neural Framework for Generalized Causal Sensitivity Analysis

1 code implementation27 Nov 2023 Dennis Frauen, Fergus Imrie, Alicia Curth, Valentyn Melnychuk, Stefan Feuerriegel, Mihaela van der Schaar

Unobserved confounding is common in many applications, making causal inference from observational data challenging.

Bounds on Representation-Induced Confounding Bias for Treatment Effect Estimation

1 code implementation19 Nov 2023 Valentyn Melnychuk, Dennis Frauen, Stefan Feuerriegel

In this paper, we propose a new, representation-agnostic refutation framework for estimating bounds on the representation-induced confounding bias that comes from dimensionality reduction (or other constraints on the representations) in CATE estimation.

Counterfactual Fairness for Predictions using Generative Adversarial Networks

no code implementations26 Oct 2023 Yuchen Ma, Dennis Frauen, Valentyn Melnychuk, Stefan Feuerriegel

It is often achieved through counterfactual fairness, which ensures that the prediction for an individual is the same as that in a counterfactual world under a different sensitive attribute.

Partial Counterfactual Identification of Continuous Outcomes with a Curvature Sensitivity Model

1 code implementation NeurIPS 2023 Valentyn Melnychuk, Dennis Frauen, Stefan Feuerriegel

We further show that existing point counterfactual identification methods are special cases of our Curvature Sensitivity Model when the bound of the curvature is set to zero.

Fair Off-Policy Learning from Observational Data

no code implementations15 Mar 2023 Dennis Frauen, Valentyn Melnychuk, Stefan Feuerriegel

Algorithmic decision-making in practice must be fair for legal, ethical, and societal reasons.

Normalizing Flows for Interventional Density Estimation

1 code implementation13 Sep 2022 Valentyn Melnychuk, Dennis Frauen, Stefan Feuerriegel

To the best of our knowledge, our Interventional Normalizing Flows are the first proper fully-parametric, deep learning method for density estimation of potential outcomes.

Estimating individual treatment effects under unobserved confounding using binary instruments

1 code implementation17 Aug 2022 Dennis Frauen, Stefan Feuerriegel

(2)~We further show that our framework asymptotically outperforms state-of-the-art plug-in IV methods for CATE estimation, in the sense that it achieves a faster rate of convergence if the CATE is smoother than the individual outcome surfaces.

Causal Transformer for Estimating Counterfactual Outcomes

1 code implementation14 Apr 2022 Valentyn Melnychuk, Dennis Frauen, Stefan Feuerriegel

In this paper, we develop a novel Causal Transformer for estimating counterfactual outcomes over time.

Estimating average causal effects from patient trajectories

1 code implementation2 Mar 2022 Dennis Frauen, Tobias Hatt, Valentyn Melnychuk, Stefan Feuerriegel

In medical practice, treatments are selected based on the expected causal effects on patient outcomes.
