Researchers from CNRS & ESSEC in France will travel to their respective Singapore campuses in June.

We are taking the opportunity to organize a mini-workshop on stats/ML at ESSEC Singapore on Friday, June 13.

If you wish to attend, you are welcome, but for logistic reasons please let me know 🙏

We know the shapes of all human proteins! That’s a definitive step in healthcare… but why?

I explain that in my latest YouTube video on the Nobel Prize in Chemistry 2024, awarded to Baker, @demishassabis and @JohnJumperSci from @GoogleDeepMind ⬇️ link the comments

I just did a Y0uTube interview of @pierrealquier.bsky.social, Professor of Statistics, and expert in statistical machine learning theory. What is the state of current AI theory? What are his tips to present his work efficiently and convince his audience in AI?

Little history of science fact: exactly 70 years ago, on April 18th 1955, Albert Einstein passed away at age 76. He did research until his last day, aiming to develop a theory unifying the laws of physics.

ML Research Paper Explained - Bet on a Coin and Achieve a Better-than-KL PAC-Bayes Bound

A simple coin-betting game can help optimize neural nets. More generally, it can help derive a bound on the error of a Bayes posterior, i.e. a PAC-Bayes bound, which is better and involves a new divergence.
Wanna know how, check out the link in the comments ⬇️

Our paper on Bayesian meta-learning with Charles Riou @charles-riou.bsky.social (University of Tokyo) and Badr-Eddine Chériéf-Abdellatif (@cnrs.bsky.social) accepted today for publication in the Journal of Machine Learning Research 😊

arxiv.org/abs/2302.11709

Bernstein's condition is a key assumption that guarantees fast rates in machine learning. For example, the Gibbs algorithm with prior $π$ has an excess risk in $O(d_π/n)$, as opposed to the standard $...
