Accounting for missing actors in interaction network inference from abundance data
Raphaëlle Momal, Stéphane Robin, Christophe Ambroise
Network inference aims at unraveling the dependency structure relating jointly observed variables. Graphical models provide a general framework to distinguish between marginal and…
Bayesian inference for network Poisson models
Sophie Donnet, Stéphane Robin
This work is motivated by the analysis of ecological interaction networks. Poisson stochastic blockmodels are widely used in this field to decipher the structure that underlies a w…
Tree-based Inference of Species Interaction Network from Abundance Data
Raphaëlle Momal, Stéphane Robin, Christophe Ambroise
The behavior of ecological systems mainly relies on the interactions between the species it involves. We consider the problem of inferring the species interaction network from abun…
A multivariate variable selection approach for analyzing LC-MS metabolomics data
M. Perrot-Dockès, C. Lévy-Leduc, J. Chiquet +5
Omic data are characterized by the presence of strong dependence structures that result either from data acquisition or from some underlying biological processes. In metabolomics,…
Detection of adaptive shifts on phylogenies using shifted stochastic processes on a tree
Paul Bastide, Mahendra Mariadassou, Stéphane Robin
Comparative and evolutive ecologists are interested in the distribution of quantitative traits among related species. The classical framework for these distributions consists of a…
Comparing change-point locations of independent profiles with application to gene annotation
Alice Cleynen, Stéphane Robin
We are interested in the comparison of transcript boundaries from cells which originated in different environments. The goal is to assess whether this phenomenon, called differenti…
