Distributed Nonconvex Constrained Optimization over Time-Varying Digraphs

Gesualdo Scutari, Ying Sun

This paper considers nonconvex distributed constrained optimization over networks, modeled as directed (possibly time-varying) graphs. We introduce the first algorithmic framework…

Distributed Big-Data Optimization via Block-wise Gradient Tracking

Ivano Notarnicola, Ying Sun, Gesualdo Scutari +1

We study distributed big-data nonconvex optimization in multi-agent networks. We consider the (constrained) minimization of the sum of a smooth (possibly) nonconvex function, i.e.,…

Decentralized Dictionary Learning Over Time-Varying Digraphs

Amir Daneshmand, Ying Sun, Gesualdo Scutari +2

This paper studies Dictionary Learning problems wherein the learning task is distributed over a multi-agent network, modeled as a time-varying directed graph. This formulation is r…

Distributed Big-Data Optimization via Block Communications

Ivano Notarnicola, Ying Sun, Gesualdo Scutari +1

We study distributed multi-agent large-scale optimization problems, wherein the cost function is composed of a smooth possibly nonconvex sum-utility plus a DC (Difference-of-Convex…

Parallel and Distributed Successive Convex Approximation Methods for Big-Data Optimization

Gesualdo Scutari, Ying Sun

Recent years have witnessed a surge of interest in parallel and distributed optimization methods for large-scale systems. In particular, nonconvex large-scale optimization problems…

Distributed Big-Data Optimization via Block-Iterative Convexification and Averaging

Ivano Notarnicola, Ying Sun, Gesualdo Scutari +1

In this paper, we study distributed big-data nonconvex optimization in multi-agent networks. We consider the (constrained) minimization of the sum of a smooth (possibly) nonconvex…
