ReSync: Riemannian Subgradient-based Robust Rotation Synchronization
Huikang Liu, Xiao Li, Anthony Man-Cho So
This work presents ReSync, a Riemannian subgradient-based algorithm for solving the robust rotation synchronization problem, which arises in various engineering applications. ReSyn…
Weakly Convex Optimization over Stiefel Manifold Using Riemannian Subgradient-Type Methods
Xiao Li, Shixiang Chen, Zengde Deng +3
We consider a class of nonsmooth optimization problems over the Stiefel manifold, in which the objective function is weakly convex in the ambient Euclidean space. Such problems are…
Incremental Methods for Weakly Convex Optimization
Xiao Li, Zhihui Zhu, Anthony Man-Cho So +1
Incremental methods are widely utilized for solving finite-sum optimization problems in machine learning and signal processing. In this paper, we study a family of incremental meth…
Convergence Analysis of Alternating Projection Method for Nonconvex Sets
Zhihui Zhu, Xiao Li
Alternating projection method has been used in a wide range of engineering applications since it is a gradient-free method (without requiring tuning the step size) and usually has…
