Federated Smoothing ADMM for Localization

Reza Mirzaeifard, Ashkan Moradi, Masahiro Yukawa +1

This paper addresses the challenge of localization in federated settings, which are characterized by distributed data, non-convexity, and non-smoothness. To tackle the scalability…

Structure Learning of Sparse GGMs over Multiple Access Networks

Mostafa Tavassolipour, Armin Karamzade, Reza Mirzaeifard +2

A central machine is interested in estimating the underlying structure of a sparse Gaussian Graphical Model (GGM) from datasets distributed across multiple local machines. The loca…
