Workshop Signal, Multiresolution and Learning on Graphs

17 déc. 2026, 08:35 → 18 déc. 2026, 18:00 Europe/Paris

Salle de Séminaire Frumam /Salle de séminaire de l’I2M (Aix-Marseille Université Campus Saint Charles )

General Information

This two-days workshop is dedicated to machine learning and data processing on networks. We will propose interactive examples of applications (such as network immunisation in epidemiology, inverse problem in neuro-science and multiscale data analysis on graphs...). We also intend to discuss related problems in cellular differenciation analyses based on single-cell measurements.

The program of Thursday, the 5th, includes two lectures by Pierre Vandergheynst, EPFL, Lausanne on the basics of signal processing on graphs, and the recent developpments on machine learning on graphs.

On Friday, the 6th, we will explore the scaling properties of Kirchhoff rooted spanning forests, with their applications through the FoSFor toolbox (Forest Screening For ...) to multiresolution analysis on graphs and to network immunisation.
