Missions
In graph Machine Learning, generative models usually focus on graph generation, an arduous task for which current models are still struggling. Paradoxically, the task of generating graph signals has been quite overlooked, even though it seems both simpler and more interpretable. Still, generating node descriptions on graph may be useful for many processes, from node ranking to non-iid graph sampling. Can these non-trivial descriptor be produced with a Machine Learning methodology? In this post-doc, we will explore the various theoretical and empirical models associated with generative models for graph signals.
Activités
Depending on the candidate, the research will be divided between theoretical studies and implementation.
Compétences
PhD in machine learning or signal processing. A good knowledge of graphs is a plus.
Contexte de travail
The candidate will be in the COMPACT team at IRISA.
