User Strategization and Trustworthy Algorithms

no code implementations29 Dec 2023 Sarah H. Cen, Andrew Ilyas, Aleksander Madry

The developers of these algorithms commonly adopt the assumption that the data generating process is exogenous: that is, how a user reacts to a given prompt (e. g., a recommendation or hiring suggestion) depends on the prompt and not on the algorithm that generated it.

A User-Driven Framework for Regulating and Auditing Social Media

no code implementations20 Apr 2023 Sarah H. Cen, Aleksander Madry, Devavrat Shah

In particular, we introduce the notion of a baseline feed: the content that a user would see without filtering (e. g., on Twitter, this could be the chronological timeline).

Matrix Estimation for Individual Fairness

no code implementations4 Feb 2023 Cindy Y. Zhang, Sarah H. Cen, Devavrat Shah

Specifically, we show that using a popular ME method known as singular value thresholding (SVT) to pre-process the data provides a strong IF guarantee under appropriate conditions.

Network Synthetic Interventions: A Causal Framework for Panel Data Under Network Interference

no code implementations20 Oct 2022 Anish Agarwal, Sarah H. Cen, Devavrat Shah, Christina Lee Yu

We propose an estimator, Network Synthetic Interventions (NSI), and show that it consistently estimates the mean outcomes for a unit under an arbitrary set of counterfactual treatments for the network.

Regret, stability & fairness in matching markets with bandit learners

no code implementations11 Feb 2021 Sarah H. Cen, Devavrat Shah

In this work, we study how competition affects the long-term outcomes of individuals as they learn.

Radar-only ego-motion estimation in difficult settings via graph matching

no code implementations25 Apr 2019 Sarah H. Cen, Paul Newman

Radar detects stable, long-range objects under variable weather and lighting conditions, making it a reliable and versatile sensor well suited for ego-motion estimation.
