Exponential convergence of a distributed divide-and-conquer algorithm for constrained convex optimization on networks

Nazar Emirov, Guohui Song, Qiyu Sun

We propose a divide-and-conquer (DAC) algorithm for constrained convex optimization over networks, where the global objective is the sum of local objectives attached to individual…

A Divide-and-Conquer Algorithm for Distributed Optimization on Networks

Nazar Emirov, Guohui Song, Qiyu Sun

In this paper, we consider networks with topologies described by some connected undirected graph and with some agents (fusion centers) equipped with processi…

Distributed algorithms to determine eigenvectors of matrices on spatially distributed networks

Nazar Emirov, Cheng Cheng, Qiyu Sun +1

Eigenvectors of matrices on a network have been used for understanding spectral clustering and influence of a vertex. For matrices with small geodesic-width, we propose a distribut…

Polynomial graph filter of multiple shifts and distributed implementation of inverse filtering

Nazar Emirov, Cheng Cheng, Junzheng Jiang +1

Polynomial graph filters and their inverses play important roles in graph signal processing. An advantage of polynomial graph filters is that they can be implemented in a distribut…
