Graph Signal Processing: Neural Nets and Beyond

ABSTRACT:
Graph Neural Networks (GNNs) have recently had a tremendous impact in Machine Learning across an impressively broad range of applications. Recent results have shown that they also have limitations (oversmoothing, lack of expressivity, ...) that are often tightly linked to the underlying graph on which they are built.

In this talk we will review the construction of graph neural networks from a graph signal processing perspective and highlight some of these limitations as well as some of the solutions proposed as remedy. We will then leverage this to construct a novel feature convolutional layer that seeks to decouple the structural and computational role of the graph.
