R-SPIDER: A Fast Riemannian Stochastic Optimization Algorithm with Curvature Independent Rate

Jingzhao Zhang, Hongyi Zhang, Suvrit Sra

We study smooth stochastic optimization problems on Riemannian manifolds. Via adapting the recently proposed SPIDER algorithm \citep{fang2018spider} (a variance reduced stochastic…
