A Stochastic Composite Gradient Method with Incremental Variance Reduction
Junyu Zhang, Lin Xiao
We consider the problem of minimizing the composition of a smooth (nonconvex) function and a smooth vector mapping, where the inner mapping is in the form of an expectation over so…

Primal-Dual Optimization Algorithms over Riemannian Manifolds: an Iteration Complexity Analysis
Junyu Zhang, Shiqian Ma, Shuzhong Zhang
In this paper we study nonconvex and nonsmooth multi-block optimization over Riemannian manifolds with coupled linear constraints. Such optimization problems naturally arise from m…

A Sparse Completely Positive Relaxation of the Modularity Maximization for Community Detection
Junyu Zhang, Haoyang Liu, Zaiwen Wen +1
In this paper, we consider the community detection problem under either the stochastic block model (SBM) assumption or the degree-correlated stochastic block model (DCSBM) assumpti…
