Time-Uniform Confidence Spheres for Means of Random Vectors

no code implementations14 Nov 2023 Ben Chugg, Hongjian Wang, Aaditya Ramdas

We derive and study time-uniform confidence spheres -- confidence sphere sequences (CSSs) -- which contain the mean of random vectors with high probability simultaneously across all sample sizes.

Auditing Fairness by Betting

1 code implementation NeurIPS 2023 Ben Chugg, Santiago Cortes-Gomez, Bryan Wilder, Aaditya Ramdas

Whereas previous work relies on a fixed-sample size, our methods are sequential and allow for the continuous monitoring of incoming data, making them highly amenable to tracking the fairness of real-world systems.

Detecting Environmental Violations with Satellite Imagery in Near Real Time: Land Application under the Clean Water Act

1 code implementation18 Aug 2022 Ben Chugg, Nicolas Rothbacher, Alex Feng, Xiaoqi Long, Daniel E. Ho

We show that this system effectively appears to detect land application (PR AUC = 0. 93) and we uncover several outlier facilities which appear to apply regularly and excessively.

Reconciling Risk Allocation and Prevalence Estimation in Public Health Using Batched Bandits

1 code implementation25 Oct 2021 Ben Chugg, Daniel E. Ho

In many public health settings, there is a perceived tension between allocating resources to known vulnerable areas and learning about the overall prevalence of the problem.

Enhancing Environmental Enforcement with Near Real-Time Monitoring: Likelihood-Based Detection of Structural Expansion of Intensive Livestock Farms

1 code implementation29 May 2021 Ben Chugg, Brandon Anderson, Seiji Eicher, Sandy Lee, Daniel E. Ho

Much environmental enforcement in the United States has historically relied on either self-reported data or physical, resource-intensive, infrequent inspections.
