Bipartite Graph Variational Auto-Encoder with Fair Latent Representation to Account for Sampling Bias in Ecological Networks

no code implementations4 Mar 2024 Emre Anakok, Pierre Barbillon, Colin Fontaine, Elisa Thebault

We propose a method to represent bipartite networks using graph embeddings tailored to tackle the challenges of studying ecological networks, such as the ones linking plants and pollinators, where many covariates need to be accounted for, in particular to control for sampling bias.

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

no code implementations11 Jun 2021 Saint-Clair Chabert-Liddell, Pierre Barbillon, Sophie Donnet

The analysis of a collection of bipartite ecological networks allows us to compare the empirical approach to our probabilistic approach, and illustrates the relevance of the latter when it comes to computing the robustness of a partially observed or incompletely sampled network.

A Stochastic Block Model Approach for the Analysis of Multilevel Networks: an Application to the Sociology of Organizations

1 code implementation23 Oct 2019 Saint-Clair Chabert-Liddell, Pierre Barbillon, Sophie Donnet, Emmanuel Lazega

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.

Stochastic Block Models for Multiplex networks: an application to networks of researchers

no code implementations26 Jan 2015 Pierre Barbillon, Sophie Donnet, Emmanuel Lazega, Avner Bar-Hen

In this paper, we extend the SBM to multiplex networks in order to obtain a clustering based on more than one kind of relationship.
