A dual approach for federated learning

Zhenan Fan, Huang Fang, Michael P. Friedlander

We study the federated optimization problem from a dual perspective and propose a new algorithm termed federated dual coordinate descent (FedDCD), which is based on a type of coord…

Cardinality-constrained structured data-fitting problems

Zhenan Fan, Huang Fang, Michael P. Friedlander

A memory-efficient framework is described for the cardinality-constrained structured data-fitting problem. Dual-based atom-identification rules are proposed that reveal the structu…

From perspective maps to epigraphical projections

Michael P. Friedlander, Ariel Goodwin, Tim Hoheisel

The projection onto the epigraph or a level set of a closed proper convex function can be achieved by finding a root of a scalar equation that involves the proximal operator as a f…
