Decentralized projected Riemannian gradient method for smooth optimization on compact submanifolds

K Deng, J Hu - arxiv preprint arxiv:2304.08241, 2023 - arxiv.org
We consider the problem of decentralized nonconvex optimization over a compact
submanifold, where each local agent's objective function defined by the local dataset is …

Decentralized Douglas-Rachford splitting methods for smooth optimization over compact submanifolds

K Deng, J Hu, H Wang - arxiv preprint arxiv:2311.16399, 2023 - arxiv.org
We study decentralized smooth optimization problems over compact submanifolds.
Recasting it as a composite optimization problem, we propose a decentralized Douglas …
