Tres sympa lire l’évaluation du jury IUF (surtout quand on est lauréat, j’avoue) et première fois dans ma vie que le seule point faible est “a bit too trendy for my taste”…si seulement j’étais si trendy que ça 🤣

Le dossier est trop jeune
Le dossier est trop théorique
Le dossier est trop numérique
Le dossier est trop “physique quantique”
Les dossier est trop “math économique”
Bon on peut se mettre d’accord ou pas? 🤣

Dual cone and polar cone are sets in the dual of a vector space. They generalize the notion of orthogonal subspace.

The Hausdorff distance quantifies how far two sets are from each other by measuring the largest minimal distance needed to cover one with the other. It captures worst-case deviation: if one set has points far from the other, the distance is large.

Large deviations for sticky-reflecting Brownian motion with boundary diffusion
We study a Schilder-type large deviation principle for sticky-reflected Brownian motion with boundary diffusion, both at the static and sample path level in the short-time limit. A sharp transition fo...

Soft(arg)max function transforms logits into probability vector. One shows that softmax (w/ temperature) converges pointwise to the argmax, selecting the most likely outcome. Essential in in multinomial logistic regression and for attention mechanisms
