WebA new contamination model for robust estimation with large high-dimensional data sets Alqallaf, Fatemah Ali Abstract Data sets can be very large, highly multidimensional and of mixed quality. This thesis provides feasible and robust methods for estimating multivariate location and scatter matrix for such data. Webeters of the Huber loss and the parameters of the Laplace distributions. Lange [12], proposed a set of potential functions for im-age reconstruction that behave like the Huber loss, but un-like the Huber loss, these functions are more than once dif-ferentiable. In this work, we propose a loss function which is similar to a potential function in ... bebas neue italic

Robust covariance and scatter matrix estimation under Huber

Web26 mei 2024 · This work establishes a general decision theory for robust statistics under Huber's $\epsilon$-contamination model, and proposes a solution using Scheff estimate to a robust two-point testing problem that leads to the construction of robust estimators adaptive to the proportion of contamination. 25 PDF View 1 excerpt, references methods Webtionally tractable while achieving near-optimal contamination dependence (i.e. dependence on the fraction of outliers ).
