The Importance of Being Discrete: Measuring the Impact of Discretization in End-to-End Differentially Private Synthetic Data

We investigate the critical yet overlooked role of discretization in end-to-end differentially private (DP) tabular synthetic data generation

The Importance of Being Discrete: Measuring the Impact of Discretization in End-to-End Differentially Private Synthetic Data Differentially Private (DP) generative marginal models are often used in the wild to release synthetic tabular datasets in lieu of sensitive data while providing formal privacy guarantees. These model...

Conditional congrats to Georgi and Sundar - their paper on Discretization in DP Synthetic Data was accepted with shepherding to CCS’25.

Very important work on an overlooked aspect of end-to-end DP pipelines.

Preprint: arxiv.org/abs/2504.06923 -- feedback welcome!

Huge congrats to @spalab.cs.ucr.edu's Georgi Ganev for receiving the Distinguished Paper Award at IEEE S&P for his work "The Inadequacy of Similarity-based Privacy Metrics: Privacy Attacks against “Truly Anonymous” Synthetic Datasets."

ACM has named 56 Distinguished Members for work that has advanced computing, fostered innovation across various fields and improved computer science education. The 2024 ACM Distinguished Members work at leading universities, corporations, and research institutions in Australia, Bangladesh, Canada, China, Cyprus, Denmark, Germany, Ireland, India, Switzerland,...

I’m proverbially humbled and manifestly honored by the ACM’s recognition as Distinguished Member.

This is obviously an achievement that would have never been possible without my amazing students and collaborators or the support and mentorship of so many people.
