Advances in Asynchronous Parallel and Distributed Optimization

no code implementations24 Jun 2020 Mahmoud Assran, Arda Aytekin, Hamid Feyzmahdavian, Mikael Johansson, Michael Rabbat

Motivated by large-scale optimization problems arising in the context of machine learning, there have been several advances in the study of asynchronous parallel and distributed optimization methods during the past decade.

Distributed Optimization

Application of Monte Carlo Tree Search in Periodic Schedule Design for Networked Control Systems

no code implementations14 Jun 2020 Burak Demirel, Arda Aytekin

We analyze the closed-loop control performance of a networked control system that consists of $N$ independent linear feedback control loops, sharing a communication network with $M$ channels ($M<N$).

Combinatorial Optimization Scheduling

A flexible framework for communication-efficient machine learning: from HPC to IoT

no code implementations13 Mar 2020 Sarit Khirirat, Sindri Magnússon, Arda Aytekin, Mikael Johansson

With the increasing scale of machine learning tasks, it has become essential to reduce the communication between computing nodes.
