Speech Title: Distributed Consensus: A Signal Processing Perspective

Abstract: Distributed consensus problem is about agreeing a set of values among multiple actors that minimize a certain distributed function. This is useful in practical distributed optimization and estimation tasks. The specific formulation of distributed consensus can adopt different constraints and assumptions, which have different properties and solutions. For instance, one class of these problems is known as graph signal processing. In this talk, I will outline several formulations of the gradient-based joint minimization of a distributed function, and its convergence properties. Such a signal processing perspective needs to be contrasted with the consensus problems considered in computer engineering, which aim at agreeing a set of values under delayed and lost messages rather than minimizing distributed functions.
