Keynote talk description:
Graphs are a classical mathematical tool that have been applied to solve various problem in domains ranging from network resource allocation to image processing. In the last decade, the development of extensions of signal processing techniques to data defined on graphs, such as that emanating from social networks, have complemented the well-stablish ideas of spectral graph theory. This has resulted in the consolation of Graph Signal Processing theory for the analysis and manipulation of signals defined on graphs. This talk will explore the fundamentals of graph filters, the workhorse of graph signal processing, and their efficient distributed implementations through applications in signal processing. Additionally, it will discuss how graph filters are applied in machine learning problems through the so-called graph convolutional networks and provide a look to current challenges and opportunities.
