This talk will be devoted to the notion of weak Kähler hyperbolicity, recently introduced by F. Bei, S. Diverio, P. Eyssidieux et S. Trapani as a substitute of the notion of Kähler hyperbolicity (Gromov, 1989). I …

Blackwell’s approachability is a general online learning framework where a Decision Maker obtains vector-valued outcomes, and aims at the convergence of the average outcome to a given “target” set. Blackwell gave a …

Geometric inverse problems are an example of one of the most natural questions we can ask ourselves in Mathematics: can one recover the shape of an object using only some specific data measured from it? Perhaps the …

Parmi toutes les intégrales divergentes, celles qui se comportent comme dx/x en x=0 (« divergences logarithmiques »), sont les plus simples et jouent un rôle central en géométrie algébrique et en arithmétique. Dans …

Nous étudions un modèle SIR à deux niveaux de mélange, à savoir un niveau global uniformément mélangeant, et un niveau local divisé en deux couches de contacts au sein des foyers et lieux de travail, respectivement. …

The study of concentration inequalities focuses on upper bounds for the probability that certain statistics of (fixed-size) random samples deviate significantly from their mean (or median). For i.i.d. samples, what …

Receiver Operating Characteristic (ROC) curves are useful for evaluating binary classification models, but difficult to use for learning since the Area Under the Curve (AUC) is a piecewise constant function of …
