CDOpt: A Python Package for a Class of Riemannian Optimization
Nachuan Xiao, Xiaoyin Hu, Xin Liu +1
Optimization over the embedded submanifold defined by constraints has attracted much interest over the past few decades due to its wide applications in various areas. Pl…
An Improved Unconstrained Approach for Bilevel Optimization
Xiaoyin Hu, Nachuan Xiao, Xin Liu +1
In this paper, we focus on the nonconvex-strongly-convex bilevel optimization problem (BLO). In this BLO, the objective function of the upper-level problem is nonconvex and possibl…
A Constraint Dissolving Approach for Nonsmooth Optimization over the Stiefel Manifold
Xiaoyin Hu, Nachuan Xiao, Xin Liu +1
This paper focus on the minimization of a possibly nonsmooth objective function over the Stiefel manifold. The existing approaches either lack efficiency or can only tackle prox-fr…
Dissolving Constraints for Riemannian Optimization
Nachuan Xiao, Xin Liu, Kim-Chuan Toh
In this paper, we consider optimization problems over closed embedded submanifolds of , which are defined by the constraints . We propose a class of constra…
