Understanding how Differentially Private Generative Models Spend their Privacy Budget. (arXiv:2305.10994v1 [cs.LG])
cs.CR updates on arXiv.org arxiv.org
Generative models trained with Differential Privacy (DP) are increasingly
used to produce synthetic data while reducing privacy risks. Navigating their
specific privacy-utility tradeoffs makes it challenging to determine which
models would work best for specific settings/tasks. In this paper, we fill this
gap in the context of tabular data by analyzing how DP generative models
distribute privacy budgets across rows and columns, arguably the main source of
utility degradation. We examine the main factors contributing to how privacy
budgets are …
