BIML: What Machine Learnt Models Reveal

19 July 2022 BIML, privacy-preserving machine learning, distribution inference, inference privacy, Gary McGraw

I gave a talk in the Berryville Institute of Machine Learning in the Barn series on What Machine Learnt Models Reveal, which is now available as an edited video: David Evans, a professor of computer science researching security and privacy at the University of Virginia, talks about data leakage risk in ML systems and different approaches used to attack and secure models and datasets. Juxtaposing adversarial risks that target records and those aimed at attributes, David shows that differential privacy cannot capture all inference risks, and calls for more research based on privacy experiments aimed at both datasets and distributions.

UVA News has an article by Audra Book on our research on security and privacy of machine learning (with some very nice quotes from several students in the group, and me saying something positive about the NSA!): Computer science professor David Evans and his team conduct experiments to understand security and privacy risks associated with machine learning, 8 September 2021. David Evans, professor of computer science in the University of Virginia School of Engineering and Applied Science, is leading research to understand how machine learning models can be compromised.

ICLR DPML 2021: Inference Risks for Machine Learning

I gave an invited talk at the Distributed and Private Machine Learning (DPML) workshop at ICLR 2021 on Inference Risks for Machine Learning.

The talk mostly covers work by Bargav Jayaraman on evaluating privacy in machine learning and connecting attribute inference and imputation, and recent work by Anshuman Suri on property inference.

Codaspy 2021 Keynote: When Models Learn Too Much
