A robust sparse representation algorithm based on adaptive joint dictionary
Sparse representation based on dictionary construction and learning methods have aroused interests in the field of face recognition. Aiming at the shortcomings of face feature dictionary not ‘clean’ and noise interference dictionary not ‘representative ...

Robust reduced-rank regression [PDF]
SummaryIn high-dimensional multivariate regression problems, enforcing low rank in the coefficient matrix offers effective dimension reduction, which greatly facilitates parameter estimation and model interpretation. However, commonly used reduced-rank methods are sensitive to data corruption, as the low-rank dependence structure between response ...

Robust regression via mutivariate regression depth [PDF]
This paper studies robust regression in the settings of Huber's $ $-contamination models. We consider estimators that are maximizers of multivariate regression depth functions. These estimators are shown to achieve minimax rates in the settings of $ $-contamination models for various regression problems including nonparametric regression, sparse ...

Huber Regression Analysis with a Semi-Supervised Method
In this paper, we study the regularized Huber regression algorithm in a reproducing kernel Hilbert space (RKHS), which is applicable to both fully supervised and semi-supervised learning schemes.

RobPer: An R Package to Calculate Periodograms for Light Curves Based on Robust Regression
An important task in astroparticle physics is the detection of periodicities in irregularly sampled time series, called light curves. The classic Fourier periodogram cannot deal with irregular sampling and with the measurement accuracies that are ...
