ORBi Open Repository and Bibliography (296.624 recursos)

In may 2007, the ULg's Administrative Board (joined in June 2007 by the FUSAGx) decided to create an institutional repository and defined a strong institutional self-archiving policy to increase the visibility, accessibility and impact of the University's publications (Board's decision). This decision led to the official launch, in November 2008, of the ORBi platform including both the Academic Bibliography and the Institutional Repository of the Wallonia-Europe University Academy.

  1. Les théorèmes d'incomplétude

    Hoyoux, Renaud
    Mémoire défendu en vue de l'obtention du titre de Master en sciences mathématiques portant sur les théorèmes d'incomplétude et constitué de quatre chapitres : le premier est un rappel des bases en logique formelle et en théorie des fonctions récursives; le second est consacré aux théorèmes d'incomplétude de Gödel; le troisième présente un exemple détaillé d'un énoncé aisé à comprendre mais néanmoins indémontrable dans l'arithmétique de Peano; le dernier explorant les possibilités de "mesure" des théorèmes indémontrables.

  2. Regularized Discriminant Analysis in Presence of Cellwise Contamination

    Aerts, Stéphanie; Wilms, Ines
    Quadratic and Linear Discriminant Analysis (QDA/LDA) are the most often applied classification rules under normality. In QDA, a separate covariance matrix is estimated for each group. If there are more variables than observations in the groups, the usual estimates are singular and cannot be used anymore. Assuming homoscedasticity, as in LDA, reduces the number of parameters to estimate. This rather strong assumption is however rarely verified in practice. Regularized discriminant techniques that are computable in high-dimension and cover the path between the two extremes QDA and LDA have been proposed in the literature. However, these procedures rely on sample covariance...
