Model selection in a sparse heterogeneous framework

Laurent Cavalier, Markus Reiß

We consider a Gaussian sequence space model $X_{λ} = f_{λ} + ξ_{λ},$ where $ξ$ has a diagonal covariance matrix $Σ=\diag(σ_λ^2)$. We consider the situation where the parameter vector $(f_λ…

Risk hull method and regularization by projections of ill-posed inverse problems

L. Cavalier, Yu. Golubev

We study a standard method of regularization by projections of the linear inverse problem $Y = A f + ε$ , where $ε$ is a white Gaussian noise, and $A$ is a known compact operator with si…
