A dependent Lindeberg central limit theorem for cluster functionals on stationary random fields
José G. Gómez-García
In this paper, we provide a central limit theorem for the finite-dimensional marginal distributions of empirical processes whose index set $\mathcal{F}…
Learning CHARME models with neural networks
José G. Gómez García, Jalal Fadili, Christophe Chesneau
In this paper, we consider a model called CHARME (Conditional Heteroscedastic Autoregressive Mixture of Experts), a class of generalized mixture of nonlinear nonparametric AR-ARCH…
Sharp Oracle Inequalities for Low-complexity Priors
Tung Duy Luu, Jalal Fadili, Christophe Chesneau
In this paper,we consider a high-dimensional statistical estimation problem in which the the number of parameters is comparable or larger than the sample size. We present a unified…
Stein Block Thresholding For Image Denoising
Christophe Chesneau, Jalal Fadili, Jean-Luc Starck
In this paper, we investigate the minimax properties of Stein block thresholding in any dimension with a particular emphasis on . Towards this goal, we consider a frame co…
