Towards Understanding the Interplay of Generative Artificial Intelligence and the Internet

1 code implementation8 Jun 2023 Gonzalo Martínez, Lauren Watson, Pedro Reviriego, José Alberto Hernández, Marc Juarez, Rik Sarkar

Our results show that the quality and diversity of the generated images can degrade over time suggesting that incorporating AI-created data can have undesired effects on future versions of generative models.

Black-Box Audits for Group Distribution Shifts

no code implementations8 Sep 2022 Marc Juarez, Samuel Yeom, Matt Fredrikson

Our experimental results on real-world datasets show that this approach is effective, achieving 80--100% AUC-ROC in detecting shifts involving the underrepresentation of a demographic group in the training set.

"You Can't Fix What You Can't Measure": Privately Measuring Demographic Performance Disparities in Federated Learning

1 code implementation24 Jun 2022 Marc Juarez, Aleksandra Korolova

As in traditional machine learning models, models trained with federated learning may exhibit disparate performance across demographic groups.

Encrypted DNS --> Privacy? A Traffic Analysis Perspective

no code implementations24 Jun 2019 Sandra Siby, Marc Juarez, Claudia Diaz, Narseo Vallina-Rodriguez, Carmela Troncoso

Virtually every connection to an Internet service is preceded by a DNS lookup which is performed without any traffic-level protection, thus enabling manipulation, redirection, surveillance, and censorship.
