Interesting "Truly private AI" that seems like the first to deliver that, up to what current technology enables.

(Yes, you have to trust the opaque magic of Trusted Execution Environments, but it is hard to see how to realistically avoid that for now.)

How to ensure anonymity of AI systems? | Faculty of Science | University of Helsinki When training artificial intelligence systems, developers need to use privacy-enhancing technologies to ensure that the subjects of the training data are not exposed, new study suggests.

ELSA Board member @ahonkela.bsky.social contributed to the paper"Impact of Dataset Properties on Membership Inference Vulnerability of Deep Transfer Learning",presented at @neuripsconf.bsky.social'25

Extract of ICLR LLM use policy with the following text highlighted: "However, new this year, if LLMs played a significant role in research ideation and/or writing to the extent that they could be regarded as a contributor, then authors should describe the precise role of the LLM in the main body of the paper in a separate section on LLM usage."

@iclr-conf.bsky.social regarding your LLM policy, can you please confirm that one does not need to have an LLM usage section in the main body of the paper if LLMs did not play a significant role as defined here?

Happy to share the recap of the #health #privacy #session at #CAMDA2025 by our amazing team!

$( varepsilon, δ)$ Considered Harmful: Best Practices for Reporting Differential Privacy Guarantees Juan Felipe Gomez, Bogdan Kulynych, Georgios Kaissis, Jamie Hayes, Borja Balle, Antti Honkela http://arxiv.org/abs/2503.10945 Current practices for reporting the level of differential privacy (DP) guarantees for machine learning (ML) algorithms provide an incomplete and potentially misleading picture of the guarantees and make it difficult to compare privacy levels across different settings. We argue for using Gaussian differential privacy (GDP) as the primary means of communicating DP guarantees in ML, with the full privacy profile as a secondary option in case GDP is too inaccurate. Unlike other widely used alternatives, GDP has only one parameter, which ensures easy comparability of guarantees, and it can accurately capture the full privacy profile of many important ML applications. To support our claims, we investigate the privacy profiles of state-of-the-art DP large-scale image classification, and the TopDown algorithm for the U.S. Decennial Census, observing that GDP fits the profiles remarkably well in all three cases. Although GDP is ideal for reporting the final guarantees, other formalisms (e.g., privacy loss random variables) are needed for accurate privacy accounting. We show that such intermediate representations can be efficiently converted to GDP with minimal loss in tightness.

Less than a week left to apply. Come join us @csaalto.bsky.social or @univhelsinkics.bsky.social #postdocjobs #ai #artificialintelligence #datascience #postdoc #algorithms #cybersecurity

Very interesting challenge on privacy of synthetic data organised together with @steglelab.bsky.social and other ELSA project partners.

Please spread the word!

This would be rather suboptimal for those living further away from big centers or working in an area where most of the relevant community is elsewhere. Unfortunately we need common meetings to avoid fragmenting the community.

I have seen some anti-peer-review takes on here, and, believe me, I understand the frustrations, but I would urge caution before doing or publicly saying anything too drastic. We live in age rife with misinformation and anti-intellectualism—not everyone wants academia to survive

Risk is twofold: 1) Europeans risk losing access to models developed outside Europe, while 2) European researchers face significant additional burden to comply with the rules. This risks violating the freedom of research.
