Decentralized Online Riemannian Optimization for Strongly Geodesically Convex Functions

Zhanyuan Cai, Emre Sahinoglu, Shahin Shahrampour

We study decentralized online optimization for strongly geodesically convex (strongly g-convex) losses on Riemannian manifolds with bounded sectional curvature, including positively curved manifolds. In centralized Riemannian optimization, strong g-convexity tightens the optimal…Read more
