Explanations are a Means to an End: A Value of Information Framework for Validating Explanations

ICML 2026poster

Explanations of model behavior are commonly evaluated via proxy properties weakly tied to the purposes explanations serve in practice. We contribute a decision theoretic framework that treats explanations as information signals valued by the expected improvement they enable on a specified decision t…

Feature Responsiveness Scores: Model-Agnostic Explanations for Recourse

ICLR 2025poster

Machine learning models routinely automate decisions in applications like lending and hiring. In such settings, consumer protection rules require companies that deploy models to explain predictions to decision subjects. These rules are motivated, in part, by the belief that explanations can promote…

Learning under Temporal Label Noise

ICLR 2025poster

Many time series classification tasks, where labels vary over time, are affected by label noise that also varies over time. Such noise can cause label quality to improve, worsen, or periodically change over time. We first propose and formalize temporal label noise, an unstudied problem for sequentia…

Understanding Fixed Predictions via Confined Regions

ICML 2025poster

Machine learning models can assign fixed predictions that preclude individuals from changing their outcome. Existing approaches to audit fixed predictions do so on a pointwise basis, which requires access to an existing dataset of individuals and may fail to anticipate fixed predictions in out-of-sa…

Prediction without Preclusion: Recourse Verification with Reachable Sets

ICLR 2024spotlight

Machine learning models are often used to decide who receives a loan, a job interview, or a public benefit. Models in such settings use features without considering their *actionability*. As a result, they can assign predictions that are \emph{fixed} -- meaning that individuals who are denied loans…

Providing Fair Recourse over Plausible Groups

AAAI 2024technical

Machine learning models now automate decisions in applications where we may wish to provide recourse to adversely affected individuals. In practice, existing methods to provide recourse return actions that fail to account for latent characteristics that are not captured in the model (e.g., age, sex,…

Participatory Personalization in Classification

NeurIPS 2023spotlight

Machine learning models are often personalized based on information that is protected, sensitive, self-reported, or costly to acquire. These models use information about people, but do not facilitate nor inform their *consent*. Individuals cannot opt out of reporting information that a model needs t…

When Personalization Harms Performance: Reconsidering the Use of Group Attributes in Prediction

ICML 2023oral

Machine learning models are often personalized with categorical attributes that define groups. In this work, we show that personalization with *group attributes* can inadvertently reduce performance at a *group level* -- i.e., groups may receive unnecessarily inaccurate predictions by sharing their…

On the Epistemic Limits of Personalized Prediction

NeurIPS 2022accept

Machine learning models are often personalized by using group attributes that encode personal characteristics (e.g., sex, age group, HIV status). In such settings, individuals expect to receive more accurate predictions in return for disclosing group attributes to the personalized model. We study wh…

Repairing without Retraining: Avoiding Disparate Impact with Counterfactual Distributions

ICML 2019oral

When the performance of a machine learning model varies over groups defined by sensitive attributes (e.g., gender or ethnicity), the performance disparity can be expressed in terms of the probability distributions of the input and output variables over each group. In this paper, we exploit this fact…
