Decentralized Optimization Over the Stiefel Manifold by an Approximate Augmented Lagrangian Function

Lei Wang, Xin Liu

In this paper, we focus on the decentralized optimization problem over the Stiefel manifold, which is defined on a connected network of $d$ agents. The objective is an average of $…
