Exponential-Wrapped Mechanisms: Differential Privacy on Hadamard Manifolds Made Practical
ICLR 2026poster
We propose a general and computationally efficient framework for achieving differential privacy (DP) on Hadamard manifolds, which are complete and simply connected Riemannian manifolds with non-positive curvature. Leveraging the Cartan-Hadamard theorem, we introduce Exponential-Wrapped Laplace and G…
