Modular decomposition of graphs and hierarchical modeling
Carenne Ludena, Miguel mendez, Nicolas Bolivar
We consider Gallai's graph Modular Decomposition theory for network analytics. On the one hand, by arguing that this is a choice tool for understanding structural and functional si…
Probability bounds for active learning in the regression problem
Ana Karina Fermin, Carenne Ludeña
In this article we consider the problem of choosing an optimal sampling scheme for the regression problem simultaneously with that of model selection. We consider a batch type appr…
Estimating the scaling function of multifractal measures and multifractal random walks using ratios
Carenne Ludeña, Philippe Soulier
In this paper, we prove central limit theorems for bias reduced estimators of the structure function of several multifractal processes, namely mutiplicative cascades, multifractal…
Adaptive complexity regularization for linear inverse problems
Jean-Michel Loubes, Carenne Ludeña
We tackle the problem of building adaptive estimation procedures for ill-posed inverse problems. For general regularization methods depending on tuning parameters, we construct a p…
-variations for multifractal fractional random walks
Carenne Ludeña
A multifractal random walk (MRW) is defined by a Brownian motion subordinated by a class of continuous multifractal random measures . In this paper we obtain an…
Adaptive estimation of linear functionals by model selection
Béatrice Laurent, Carenne Ludeña, Clémentine Prieur
We propose an estimation procedure for linear functionals based on Gaussian model selection techniques. We show that the procedure is adaptive, and we give a non asymptotic oracle…
