Abstract:We consider the decentralized minimization of a separable objectivewhere the variables are coupled through an affine constraintWe assume that the functions f i , matrices A i , and vectors b i are stored locally by the nodes of a computational network, and that the functions f i are smooth and strongly convex. This problem has significant applications in resource allocation and systems control and can also arise in distributed machine learning. We propose lower complexity bounds for decentralized optimization … Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
