From Predictive Algorithms to Automatic Generation of Anomalies

no code implementations15 Apr 2024 Sendhil Mullainathan, Ashesh Rambachan

Facing a similar problem -- how to extract theoretical insights from their intuitions -- researchers often turned to ``anomalies:'' constructed examples that highlight flaws in an existing theory and spur the development of new ones.

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.

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."

Fairness

Design-Based Uncertainty for Quasi-Experiments

no code implementations3 Aug 2020 Ashesh Rambachan, Jonathan Roth

An interesting feature of our framework is that conventional standard errors tend to become more conservative when treatment probabilities vary more across units, i. e. when there is more selection into treatment.
