Dear AATRN Networks Seminar members,
Our next online seminar will be on Tuesday, 3rd of February, at 5pm CET / 11am Eastern Time.
Speaker: Manuel Lecha
Title: Learning with Directed Higher-Order Structure: Applications to Brain Stimulus Classification
Abstract: Graph Neural Networks learn representations from graph-structured data by exploiting relational
and locality-based inductive biases, with successful applications in chemistry, social networks, and neuroscience. Beyond pairwise interactions, higher-order learning frameworks leverage richer adjacency structures induced by higher-order constructions—such
as simplicial or cell complexes—to propagate information over signals supported on higher-order entities. In this talk, we focus on directed higher-order structures to design more expressive inductive biases for neural architectures. Since neural systems exhibit
inherently directional and higher-order interaction patterns arising from asymmetric synaptic transmission and co-activation dynamics, directed topological message passing provides a principled framework for effective brain stimulus classification.
