Riemannian Zeroth-Order Gradient Estimation with Structure-Preserving Metrics for Geodesically Incomplete Manifolds
Shaocong Ma, Heng Huang
In this paper, we study Riemannian zeroth-order optimization in settings where the underlying Riemannian metric is geodesically incomplete, and the goal is to approximate stati…
