Differentially Private Neural Tangent Kernels for Privacy-Preserving Data Generation

arXiv:2303.01687v2 Announce Type: replace
Abstract: Maximum mean discrepancy (MMD) is a particularly useful distance metric for differentially private data generation: when used with finite-dimensional features it allows us to summarize and privatize the data distribution once, which we can repeatedly use during generator training without further privacy loss. An important question in this framework is, then, what features are useful to distinguish between real and synthetic data distributions, and whether those enable us to generate quality synthetic data.
