Alexander Rogozin, Demyan Yarmoshik, Ksenia Kopylova, Alexander Gasnikov

摘要:

分散式优化是分布式信号处理和传感以及隐私保护和大规模机器学习中使用的常见范例。假设几个计算实体局部地持有目标函数并且通过网络连接。智能体的目标是通过梯度更新和与近邻交换信息来共同最小化局部目标的总和。分散优化理论在文献中已经相当成熟。特别地,它包括下界和最优算法。在本文中,我们假设,随着一个目标,每个节点也持有仿射约束。讨论了仿射约束下分散最优化问题的几种原始和对偶方法。

英文摘要:

Decentralized optimization is a common paradigm used in distributed signal processing and sensing as well as privacy-preserving and large-scale machine learning. It is assumed that several computational entities locally hold objective functions and are connected by a network. The agents aim to commonly minimize the sum of the local objectives subject by making gradient updates and exchanging information with their immediate neighbors. Theory of decentralized optimization is pretty well-developed in the literature. In particular, it includes lower bounds and optimal algorithms. In this paper, we assume that along with an objective, each node also holds affine constraints. We discuss several primal and dual approaches to decentralized optimization problem with affine constraints.
