Researchers have developed a new differentially private synthetic data algorithm called SPLICE, which offers strong global distributional guarantees even in high-dimensional datasets. The algorithm measures noisy sliced Chebyshev polynomial moments and fits a distribution to match, achieving a Sliced Wasserstein-1 distance of O(1/sqrt(n)) from the target distribution, independent of data dimension. A practical implementation of SPLICE demonstrates state-of-the-art performance on benchmarks compared to existing differentially private synthetic data methods. AI
