EE4540 Distributed signal processingNot running
This is a course on decentralized signal processing techniques. Due to the explosion in size and complexity of modern datasets, it is increasingly important to be able to solve problems with a very large number of features or training examples. In industry, this trend has been referred to as �Big Data�, and it has had a significant impact in areas as varied as artificial intelligence, internet applications, computational biology, medicine, finance, marketing, journalism, network analysis, weather forecast, telecommunication, and logistics. As a result, both the decentralized collection or storage of these data sets as well as accompanying distributed solution methods are either necessary or at least highly desirable.
In this course we will focus on three signal processing techniques for decentralized processing: one based on distributed consensus, one on graphical models and one based on convex optimization. We will consider the following topics: synchronous and asynchronous versions of distributes averaging, gossip algorithms (randomized, geographic, broadcast, etc.), graphical models, probabilistic inference, message passing, min-sum/max-product algorithm, Jacobi and Gauss-Seidel algorithm, convex optimization, dual ascent, dual decomposition, alternating direction method of multipliers (ADMM) and primal-dual method of multipliers (PDMM).
