About

Welcome to the Privacy-Preserving Machine Learning Workshop at EurIPS 2025!

The success of machine learning depends on access to large amounts of training data, which often contains sensitive information. This raises issues of legality, competitiveness, and privacy when data is exposed. Neural networks are known to be vulnerable to privacy attacks, a concern that has recently become more visible with large language models (LLMs), where attacks can be carried out directly through prompting. Differential privacy, the gold standard for privacy-preserving learning, has improved in terms of privacy–utility trade-offs thanks to new trust models and algorithms. However, there are still many open questions on how to bridge the gap between attacks and defenses, from developing auditing methods and more effective attacks to the growing interest in machine unlearning.

Which models best reflect real-world scenarios? How can methods scale to deep learning and foundation models? How are unlearning, auditing, and privacy-preserving machine learning connected, and how can these lines of work be brought together?

This workshop will bring together researchers from academia and industry working on differential privacy, machine unlearning, privacy auditing, privacy attacks, and related topics.

This workshop is non-archival and will not have official proceedings. Workshop submissions can be submitted to other venues. We welcome ongoing and unpublished work, including papers that are under review at the time of submission. We do not accept submissions that have already been accepted for publication in other venues with archival proceedings. The titles of accepted papers will be published on the website.

We are looking for reviewers to help ensure a fair and constructive review process.
Each reviewer will be asked to review at most 3 papers.
