Stochastic Block Model

Learning common structures in a collection of networks. An application to food webs

Let a collection of networks represent interactions within several (social or ecological) systems. We pursue two objectives: identifying similarities in the topological structures that are held in common between the networks and clustering the …

Statistical learning of collections of networks with applications in ecology and sociology

This thesis deals with the development of statistical methods for the analysis of collections of interaction networks through three original contributions. Interaction networks are a natural way to represent in graph form the exchanges or …

Statistical learning of collections of networks with applications in ecology and sociology

A Stochastic Block Model for collection of networks: Do the networks share a common structure?

Impact of the mesoscale structure of a bipartite ecological interaction network on its robustness through a probabilistic modeling

The robustness of an ecological network quantifies the resilience of the ecosystem it represents to species loss. It corresponds to the proportion of species that are disconnected from the rest of the network when extinctions occur sequentially. …

A stochastic block model approach for the analysis of multilevel networks: An application to the sociology of organizations

A multilevel network is defined as the junction of two interaction networks, one level representing the interactions between individuals and the other the interactions between organizations. The levels are linked by an affiliation relationship, each …
