On adaptive wavelet estimation of a class of weighted densities
Fabien Navarro, Christophe Chesneau, Jalal Fadili
We investigate the estimation of a weighted density taking the form , where denotes an unknown density, the associated distribution function and is a known (no…

Local Behavior of Sparse Analysis Regularization: Applications to Risk Estimation
Samuel Vaiter, Charles Deledalle, Gabriel Peyré +2
In this paper, we aim at recovering an unknown signal x0 from noisy L1measurements y=Phi*x0+w, where Phi is an ill-conditioned or singular linear operator and w accounts for some n…

Block thresholding for wavelet-based estimation of function derivatives from a heteroscedastic multichannel convolution model
Fabien Navarro, Christophe Chesneau, Jalal Fadili +1
We observe heteroscedastic stochastic processes , where for any and , is the convolution product of an unknown functi…
