Researchers have developed a new method for generating differentially private synthetic data using generalized moment matching. This technique estimates moments privately, fits a probability measure, and then samples synthetic records. The framework is applicable to various integral probability metrics, including Chebyshev moment matching for Wasserstein distance, maximum mean discrepancy with Matern and Laplace kernels, and sliced Wasserstein distance. The resulting synthetic data generation rates are shown to be nearly minimax optimal for fixed dimensions. AI
