#Optimisation | Jérôme Bolte, professeur à l’Université Toulouse Capitole et membre de la TSE-R, nous présente les algorithmes d'optimisation. ➡️youtube.com/watch?v=tjkgIr… 🤝TSE

Officially on blue sky lukenen.bsky.social See you there 😉

Pensée pour Brahim Bouraam. Il n’a pas pu vivre jusqu’à 96 ans. Il avait 29 ans quand il a été jeté dans le Seine par un adepte du FN, le 1er Mai 1995, en marge d’une manifestation organisée par Le Pen père.

Oldies but goldies: R. T Rockafellar, Monotone Operators and the Proximal Point Algorithm, 1976. Proximal point algorithm is the most fundamental non-smooth optimization method and is the basis for many other proximal methods (FB, DR, ADMM, Dykstra, etc). en.wikipedia.org/wiki/Proximal_…

Brownian motion is the fundamental martingale that arises in almost all areas of mathematics with a stochastic aspect, used in biology, passing by statistical mechanics and diffusion model. tandfonline.com/doi/abs/10.108…

Enjoyed giving this last lecture for this academic year in Orsay lucanenna.github.io/teaching/anum/…

Optimal quantization solves a minimum Optimal Transport projection. Lloyd algorithm computes a stationary point of this non-convex energy (see work by Canas and Rosasco arxiv.org/pdf/1209.1077.…)

J’ai terminé mon service d’enseignement mais pas de pause car il faut rédiger les dossiers prof…en fait suis un hamster enseignements->dossiers->enseignements->… 🐹

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

Since on Monday I will have a paper in probability on Arxiv, can I officially apply also for full professorship in probability?🤣🤣🤣🤣

It’s preprint day! Large deviations for sticky-reflecting Brownian motion with boundary diffusion - Archive ouverte HAL hal.science/hal-04895784

This is too much! It is time to leave this place! Bye 👋

C’était une campagne de (pas) recrutement prof assez traumatisante 😅 il me faudra une année pour me reprendre 🤣

IUF👍

Very excited and proud of this incredible team effort #compchem

So proud of this work done with an amazing team!

Join our team!

It’s preprint day! Convergence rates for regularized unbalanced optimal transport: the discrete case - Inria - Institut national de recherche en sciences et technologies du numérique inria.hal.science/hal-05157120

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 🤣
