[Modèles Statistiques pour la classification non-supervisée des sommets d’un graphe et application à un réseau d’interactions de protéines]
La classification non-supervisée des noeuds d’un graphe donne des éléments essentiels sur l’architecture d’un réseau. Il existe des différences d’approche entre les communautés scientifiques (informaticiens, physiciens et statisticiens) qui se sont attaqués à cette question. Nous présentons ici les travaux récents de la communauté des statisticiens, basés sur des modèles de graphes aléatoires hétérogènes et nous analysons un grand réseau d’interactions de protéines avec un modèle de ce type.
Clustering the nodes of a graph allows to analyze the topology of a network. At least three scientific communities (Computer science, Physics and Statistics) proposed some methods to go ahead. We give here an overview about the last developments about heterogeneous random graph models proposed by the statisticians. The Stochastic Block Model is applied to analyze a large Protein-Protein Interaction network
