Robust structure learning using multivariate T-distributions

We first investigate the order of magnitude of the worst-case risk of three types of estimators of a linear functional: the greedy subset selection (GSS), the group (hard and

In the first scenario, we focus on the mean estimation, m, by comparing the ECME proposed algorithm with the minimum covariance determinant [16], the Marona’s or-

Considering the estimation issue of the MGGD parameters, the main contribution of this paper is to prove that the maximum likelihood estimator (MLE) of the scatter matrix exists and

L’archive ouverte pluridisciplinaire HAL, est destinée au dépôt et à la diffusion de documents scientifiques de niveau recherche, publiés ou non, émanant des

Using this result, we prove that when points are Poisson distributed on a surface under the same hypothesis, whose expected number of vertices is λ, the expected size is O(λ log 2

Vibration measurements were also taken in Room 103 (Fig. 2) which contained two electron microscopes; a Cambridge Scanning Micro-. scope and a Phillips 100 transmission
