Single-loop $\mathcal{O}(\hat{I}{\mu }^{-3})$ stochastic smoothing algorithms for nonsmooth Riemannian optimization

Kangkang Deng, Zheng Peng, Weihe Wu

In this paper, we develop two Riemannian stochastic smoothing algorithms for nonsmooth optimization problems on Riemannian manifolds, addressing distinct forms of the nonsmooth ter…
