Compressed Gradient Methods with Hessian-Aided Error Compensation
Sarit Khirirat, Sindri Magnússon, Mikael Johansson
The emergence of big data has caused a dramatic shift in the operating regime for optimization algorithms. The performance bottleneck, which used to be computations, is now often c…
Distributed Optimal Voltage Control with Asynchronous and Delayed Communication
Sindri Magnússon, Guannan Qu, Na Li
The increased penetration of volatile renewable energy into distribution networks necessities more efficient distributed voltage control. In this paper, we design distributed feedb…
On Maintaining Linear Convergence of Distributed Learning and Optimization under Limited Communication
Sindri Magnússon, Hossein Shokri-Ghadikolaei, Na Li
In distributed optimization and machine learning, multiple nodes coordinate to solve large problems. To do this, the nodes need to compress important algorithm information to bits…
