Towards Scalable Algorithms for Distributed Optimization and Learning
Abstract: Increasing amounts of data generated by modern complex systems such as the energy grid, social media platforms, sensor networks, and cloud-based services call for attention to distributed data processing, in particular, for the design of scalable algorithms that take into account storage and communication constraints and help to make coordinated decisions. In this talk, we present recently proposed distributed algorithms with near-optimal convergence rates for optimization problems over networks, where data is stored distributedly. We focus on scalable algorithms and show they can achieve the same rates as their centralized counterparts, with an additional cost related to the structure of the network. We provide application examples to distributed inference and learning, and computational optimal transport.
