Accelerated Distributed Dual Averaging Over Evolving Networks of Growing Connectivity
收藏 引用
IEEE TRANSACTIONS ON SIGNAL PROCESSING 2018年 第7期66卷 1845-1859页
作者: Liu, Sijia Chen, Pin-Yu Hero, Alfred O. Univ Michigan Ann Arbor MI 48109 USA IBM Res MIT IBM Watson AI Lab Cambridge MA 02142 USA IBM Thomas J Watson Res Ctr AI Fdn Learning Grp Yorktown Hts NY 10598 USA
We consider the problem of accelerating distributed optimization in multi-agent networks by sequentially adding edges. Specifically, we extend the distributed dual averaging (DDA) subgradient algorithm to evolving net... 详细信息

subgradient Method for Convex Feasibility on Riemannian Manifolds
收藏 引用
JOURNAL OF OPTIMIZATION THEORY AND APPLICATIONS 2012年 第3期152卷 773-785页
作者: Bento, Glaydston C. Melo, Jefferson G. IME Univ Fed Goias BR-74001970 Goiania Go Brazil
In this paper, a subgradient type algorithm for solving convex feasibility problem on Riemannian manifold is proposed and analysed. The sequence generated by the algorithm converges to a solution of the problem, provi... 详细信息
