Asynchronous Distributed Optimization with Delay-free Parameters

no code implementations11 Dec 2023 Xuyang Wu, Changxin Liu, Sindri Magnusson, Mikael Johansson

In contrast to alternatives, our algorithms can converge to the fixed point set of their synchronous counterparts using step-sizes that are independent of the delays.

Leakage Localization in Water Distribution Networks: A Model-Based Approach

no code implementations31 Mar 2022 Ludvig Lindstrom, Sebin Gracy, Sindri Magnusson, Henrik Sandberg

Finally, assuming the existence of a single leak, for a network comprising of more than one pipe and assuming that the network has a tree structure, we provide a systematic procedure for determining the leak location, the leak exponent, and the leak constant

Delay-adaptive step-sizes for asynchronous learning

no code implementations17 Feb 2022 Xuyang Wu, Sindri Magnusson, Hamid Reza Feyzmahdavian, Mikael Johansson

In this paper, we show that it is possible to use learning rates that depend on the actual time-varying delays in the system.

Communication-efficient Variance-reduced Stochastic Gradient Descent

no code implementations10 Mar 2020 Hossein S. Ghadikolaei, Sindri Magnusson

Moreover, it is much more robust to quantization (in terms of maintaining the true minimizer and the convergence rate) than the state-of-the-art algorithms for solving distributed optimization problems.
