Distributed Dictionary Learning
Amir Daneshmand, Gesualdo Scutari, Francisco Facchinei
The paper studies distributed Dictionary Learning (DL) problems where the learning task is distributed over a multi-agent network with time-varying (nonsymmetric) connectivity. Thi…
Distributed Nonconvex Optimization for Sparse Representation
Ying Sun, Gesualdo Scutari
We consider a non-convex constrained Lagrangian formulation of a fundamental bi-criteria optimization problem for variable selection in statistical learning; the two criteria are a…
Joint Uplink/Downlink Optimization for Backhaul-Limited Mobile Cloud Computing with User Scheduling
Ali Al-Shuwaili, Osvaldo Simeone, Alireza Bagheri +1
Mobile cloud computing enables the offloading of computationally heavy applications, such as for gaming, object recognition or video processing, from mobile users (MUs) to cloudlet…
Asynchronous Parallel Algorithms for Nonconvex Optimization
Loris Cannelli, Francisco Facchinei, Vyacheslav Kungurtsev +1
We propose a new asynchronous parallel block-descent algorithmic framework for the minimization of the sum of a smooth nonconvex function and a nonsmooth convex one, subject to bot…
Distributed Nonconvex Multiagent Optimization Over Time-Varying Networks
Ying Sun, Gesualdo Scutari, Daniel Palomar
We study nonconvex distributed optimization in multiagent networks where the communications between nodes is modeled as a time-varying sequence of arbitrary digraphs. We introduce…
NEXT: In-Network Nonconvex Optimization
Paolo Di Lorenzo, Gesualdo Scutari
We study nonconvex distributed optimization in multi-agent networks with time-varying (nonsymmetric) connectivity. We introduce the first algorithmic framework for the distributed…
