Predictive Performance Comparison of Decision Policies Under Confounding

no code implementations1 Apr 2024 Luke Guerdan, Amanda Coston, Kenneth Holstein, Zhiwei Steven Wu

However, it is challenging to compare predictive performance against an existing decision-making policy that is generally under-specified and dependent on unobservable factors.

Recentering Validity Considerations through Early-Stage Deliberations Around AI and Policy Design

no code implementations26 Mar 2023 Anna Kawakami, Amanda Coston, Haiyi Zhu, Hoda Heidari, Kenneth Holstein

AI-based decision-making tools are rapidly spreading across a range of real-world, complex domains like healthcare, criminal justice, and child welfare.

Counterfactual Prediction Under Outcome Measurement Error

1 code implementation22 Feb 2023 Luke Guerdan, Amanda Coston, Kenneth Holstein, Zhiwei Steven Wu

We also develop a method for estimating treatment-dependent measurement error parameters when these are unknown in advance.

Ground(less) Truth: A Causal Framework for Proxy Labels in Human-Algorithm Decision-Making

no code implementations13 Feb 2023 Luke Guerdan, Amanda Coston, Zhiwei Steven Wu, Kenneth Holstein

In this paper, we identify five sources of target variable bias that can impact the validity of proxy labels in human-AI decision-making tasks.

Robust Design and Evaluation of Predictive Algorithms under Unobserved Confounding

no code implementations19 Dec 2022 Ashesh Rambachan, Amanda Coston, Edward Kennedy

We propose a unified methodology for the robust design and evaluation of predictive algorithms in selectively observed data under such unobserved confounding.

The role of the geometric mean in case-control studies

no code implementations19 Jul 2022 Amanda Coston, Edward H. Kennedy

We provide a new definition of collapsibility that makes this choice of aggregation method explicit, and we demonstrate that the odds ratio is collapsible under geometric aggregation.

A Validity Perspective on Evaluating the Justified Use of Data-driven Decision-making Algorithms

no code implementations30 Jun 2022 Amanda Coston, Anna Kawakami, Haiyi Zhu, Ken Holstein, Hoda Heidari

Recent research increasingly brings to question the appropriateness of using predictive tools in complex, real-world tasks.

Characterizing Fairness Over the Set of Good Models Under Selective Labels

1 code implementation2 Jan 2021 Amanda Coston, Ashesh Rambachan, Alexandra Chouldechova

We develop a framework for characterizing predictive fairness properties over the set of models that deliver similar overall performance, or "the set of good models."

Neural Topic Models with Survival Supervision: Jointly Predicting Time-to-Event Outcomes and Learning How Clinical Features Relate

no code implementations15 Jul 2020 Linhong Li, Ren Zuo, Amanda Coston, Jeremy C. Weiss, George H. Chen

As an alternative, we present an interpretable neural network approach to jointly learn a survival model to predict time-to-event outcomes while simultaneously learning how features relate in terms of a topic model.

Conditional Learning of Fair Representations

1 code implementation ICLR 2020 Han Zhao, Amanda Coston, Tameem Adel, Geoffrey J. Gordon

We propose a novel algorithm for learning fair representations that can simultaneously mitigate two notions of disparity among different demographic subgroups in the classification setting.

Counterfactual Risk Assessments, Evaluation, and Fairness

1 code implementation30 Aug 2019 Amanda Coston, Alan Mishler, Edward H. Kennedy, Alexandra Chouldechova

These tools thus reflect risk under the historical policy, rather than under the different decision options that the tool is intended to inform.
