Doubly Robust Inference in Causal Latent Factor Models

no code implementations18 Feb 2024 Alberto Abadie, Anish Agarwal, Raaz Dwivedi, Abhin Shah

This article introduces a new estimator of average treatment effects under unobserved confounding in modern data-rich environments featuring large numbers of units and outcomes.

On Computationally Efficient Learning of Exponential Family Distributions

no code implementations12 Sep 2023 Abhin Shah, Devavrat Shah, Gregory W. Wornell

While the traditional maximum likelihood estimator for this class of exponential family is consistent, asymptotically normal, and asymptotically efficient, evaluating it is computationally hard.

Group Fairness with Uncertainty in Sensitive Attributes

no code implementations16 Feb 2023 Abhin Shah, Maohao Shen, Jongha Jon Ryu, Subhro Das, Prasanna Sattigeri, Yuheng Bu, Gregory W. Wornell

To overcome this limitation, we propose a bootstrap-based algorithm that achieves the target level of fairness despite the uncertainty in sensitive attributes.

On counterfactual inference with unobserved confounding

no code implementations14 Nov 2022 Abhin Shah, Raaz Dwivedi, Devavrat Shah, Gregory W. Wornell

Given an observational study with $n$ independent but heterogeneous units, our goal is to learn the counterfactual distribution for each unit using only one $p$-dimensional sample per unit containing covariates, interventions, and outcomes.

Optimal Compression of Locally Differentially Private Mechanisms

no code implementations29 Oct 2021 Abhin Shah, Wei-Ning Chen, Johannes Balle, Peter Kairouz, Lucas Theis

Compressing the output of \epsilon-locally differentially private (LDP) randomizers naively leads to suboptimal utility.

Selective Regression Under Fairness Criteria

1 code implementation28 Oct 2021 Abhin Shah, Yuheng Bu, Joshua Ka-Wing Lee, Subhro Das, Rameswar Panda, Prasanna Sattigeri, Gregory W. Wornell

Selective regression allows abstention from prediction if the confidence to make an accurate prediction is not sufficient.

A Computationally Efficient Method for Learning Exponential Family Distributions

no code implementations NeurIPS 2021 Abhin Shah, Devavrat Shah, Gregory W. Wornell

In this work, we propose a computationally efficient estimator that is consistent as well as asymptotically normal under mild conditions.

Finding Valid Adjustments under Non-ignorability with Minimal DAG Knowledge

1 code implementation22 Jun 2021 Abhin Shah, Karthikeyan Shanmugam, Kartik Ahuja

Our main result strengthens these prior results by showing that under a different expert-driven structural knowledge -- that one variable is a direct causal parent of treatment variable -- remarkably, testing for subsets (not involving the known parent variable) that are valid back-doors is equivalent to an invariance test.

Treatment Effect Estimation using Invariant Risk Minimization

2 code implementations13 Mar 2021 Abhin Shah, Kartik Ahuja, Karthikeyan Shanmugam, Dennis Wei, Kush Varshney, Amit Dhurandhar

Inferring causal individual treatment effect (ITE) from observational data is a challenging problem whose difficulty is exacerbated by the presence of treatment assignment bias.

On Learning Continuous Pairwise Markov Random Fields

no code implementations28 Oct 2020 Abhin Shah, Devavrat Shah, Gregory W. Wornell

We consider learning a sparse pairwise Markov Random Field (MRF) with continuous-valued variables from i. i. d samples.
