Batiste Le Bars: Event detection and structure inference for graph vectors

This thesis addresses different problems around the analysis and the modeling of graph signals i.e. vector data that are observed over graphs. In particular, we are interested in two tasks. The first one is the problem
of event detection, i.e. anomaly or changepoint detection, in a set of graph vectors. The second task concerns the inference of the graph structure underlying the observed graph vectors contained in a data set.

Mathilde Fekom : Sequential Resource Allocation for network diffusion control

In this thesis we extend the Dynamic Resource Allocation (DRA) problem and propose a multi-round dynamic control framework, which we realize through the derived Sequential DRA model (SDRA). Contrary to the standard full-information and full-access DRA considerations, at each intervention round, the DM gains information and access only a fraction of the nodes, in a sequential fashion.
