Researchers have developed a new method using kernel Stein discrepancies to provide certificates for Rényi differential privacy. This approach, particularly useful outside the Gaussian setting, allows for the derivation of task-aware privacy certificates by focusing the kernel on relevant privacy directions. The paper provides exact identities for Gaussian and Laplace mechanisms and bounds for exponential mechanisms, demonstrating separate task-aware guarantees with an example using real data. AI
