Optimal Algorithms for Distributed Optimization
César A. Uribe, Soomin Lee, Alexander Gasnikov +1
In this paper, we study the optimal convergence rate for distributed convex optimization problems in networks. We model the communication restrictions imposed by the network as a s…
Distributed Active State Estimation with User-Specified Accuracy
Charles Freundlich, Soomin Lee, Michael M. Zavlanos
In this paper, we address the problem of controlling a network of mobile sensors so that a set of hidden states are estimated up to a user-specified accuracy. The sensors take meas…
On the Sublinear Regret of Distributed Primal-Dual Algorithms for Online Constrained Optimization
Soomin Lee, Michael M. Zavlanos
This paper introduces consensus-based primal-dual methods for distributed online optimization where the time-varying system objective function is given as the sum…
Complexity Certification of a Distributed Augmented Lagrangian Method
Soomin Lee, Nikolaos Chatzipanagiotis, Michael M. Zavlanos
In this paper we present complexity certification results for a distributed Augmented Lagrangian (AL) algorithm used to solve convex optimization problems involving globally couple…
Communication-Efficient Algorithms for Decentralized and Stochastic Optimization
Guanghui Lan, Soomin Lee, Yi Zhou
We present a new class of decentralized first-order methods for nonsmooth and stochastic optimization problems defined over multiagent networks. Considering that communication is a…
