WebSep 21, 2016 · In this letter, we consider a class of generalized multivariate Huber (GMH) loss functions. Our goal is parameter estimation in linear models contaminated by non-Gaussian noise. We assume access to a secondary dataset of independent noise realizations, and we use these data to fit a convex GMH function that will then lead to … WebMar 31, 2024 · functionXal-class: Class "functionXal" of Functionals (of Psi-like functions) functionX-class: Class "functionX" of Psi-like Vectorized Functions; glmrob: Robust Fitting of Generalized Linear Models; glmrob.control: Controlling Robust GLM Fitting by Different Methods; h.alpha.n: Compute h, the subsample size for MCD and LTS

WebTo define the generalized MC (GMC) penalty we first define a multivariate generalized Huber function. The resulting cost function can be minimized by proximal algorithms comprising simple computations. The effectiveness of the GMC penalty is illustrated in a denoising example.
