USENIX Security Symposium 2019
Bargav Jayaraman presented our paper on Evaluating Differentially Private Machine Learning in Practice at the 28th USENIX Security Symposium in Santa Clara, California. Summary by Lea Kissner: Hey it's the results! pic.twitter.com/ru1FbkESho — Lea Kissner (@LeaKissner) August 17, 2019 Also, great to see several UVA folks at the conference including: Sam Havron (BSCS 2017, now a PhD student at Cornell) presented a paper on the work he and his colleagues have done on computer security for victims of intimate partner violence.Google Security and Privacy Workshop
I presented a short talk at a workshop at Google on Adversarial ML: Closing Gaps between Theory and Practice (mostly fun for the movie of me trying to solve Google’s CAPTCHA on the last slide): Getting the actual screencast to fit into the limited time for this talk challenged the limits of my video editing skills. I can say with some confidence, Google does donuts much better than they do cookies!Brink Essay: AI Systems Are Complex and Fragile. Here Are Four Key Risks to Understand.
Brink News (a publication of the The Atlantic) published my essay on the risks of deploying AI systems. Artificial intelligence technologies have the potential to transform society in positive and powerful ways. Recent studies have shown computing systems that can outperform humans at numerous once-challenging tasks, ranging from performing medical diagnoses and reviewing legal contracts to playing Go and recognizing human emotions. Despite these successes, AI systems are fundamentally fragile — and the ways they can fail are poorly understood.Google Federated Privacy 2019: The Dragon in the Room
I’m back from a very interesting Workshop on Federated Learning and Analytics that was organized by Peter Kairouz and Brendan McMahan from Google’s federated learning team and was held at Google Seattle. For the first part of my talk, I covered Bargav’s work on evaluating differentially private machine learning, but I reserved the last few minutes of my talk to address the cognitive dissonance I felt being at a Google meeting on privacy.Graduation 2019

How AI could save lives without spilling medical secrets
I’m quoted in this article by Will Knight focused on the work Oasis Labs (Dawn Song’s company) is doing on privacy-preserving medical data analysis: How AI could save lives without spilling medical secrets, MIT Technology Review, 14 May 2019. “The whole notion of doing computation while keeping data secret is an incredibly powerful one,” says David Evans, who specializes in machine learning and security at the University of Virginia. When applied across hospitals and patient populations, for instance, machine learning might unlock completely new ways of tying disease to genomics, test results, and other patient information.Cost-Sensitive Adversarial Robustness at ICLR 2019
Xiao Zhang will present Cost-Sensitive Robustness against Adversarial Examples on May 7 (4:30-6:30pm) at ICLR 2019 in New Orleans.
