+  description: "This seminar introduces the transition from traditional neural networks to Graph Neural Networks (GNNs), highlighting the limitations of MLPs in modeling relational data. It presents graphs as a natural representation for such data and describes GNNs through the message passing paradigm. Key architectures, challenges, and current research directions, including spatio-temporal graph learning, are briefly discussed."

   description: "This seminar provides an accessible introduction to the mathematical concept of sheaves. We will focus in particular on sheaves defined on graphs, explaining their intuition and basic properties in a simple and approachable way. Building on this foundation, we will introduce Sheaf Neural Networks, a recent extension of Graph Neural Networks that uses sheaf structures."
