arXiv:2606.11283v1 Announce Type: cross Abstract: We study the problem of generating synthetic data under differential privacy. We establish fixed-parameter tractability (FPT) for this problem where the parameter is the treewidth of the query family's incidence graph. Our algorithms attain optimal error rates across all regimes and are realized by two different approaches: the first is based on linear programming (LP) and the FPT of the separation problem for the LP dual; the second is based on a subsampled private multiplicative weights method, where we obtain FPT for sampling from Gibbs dist
The increasing focus on privacy-preserving AI and the development of differential privacy techniques are driving research into robust and efficient synthetic data generation. This publication demonstrates significant algorithmic advancements.
This research provides a more efficient and theoretically sound method for generating private synthetic data, which is crucial for ethical AI development, data sharing, and compliance with privacy regulations.
The ability to generate high-quality synthetic data with strong privacy guarantees at optimal error rates, especially for complex query families, becomes more practical and scalable.
