Efficient Diffusion Models for Symmetric Manifolds

Oren Mangoubi, Neil He, Nisheeth K. Vishnoi

We introduce a framework for designing efficient diffusion models for -dimensional symmetric-space Riemannian manifolds, including the torus, sphere, special orthogonal group an…

Private Low-Rank Approximation for Covariance Matrices, Dyson Brownian Motion, and Eigenvalue-Gap Bounds for Gaussian Perturbations

Oren Mangoubi, Nisheeth K. Vishnoi

We consider the problem of approximating a covariance matrix with a rank- matrix under -differential privacy. We present and analyze a complex…
