Ten days ago I took part in the SEINE AI 2026 workshop in Jouy-en-Josas, near Paris (homestead of HEC), organised by the Huawei Paris Research Center.. In which I was invited to speak, even though I felt sort of an outlier given the deeply machine-learning, entreprenarial orientation of the meeting, with its theme being Building the Agentic Future of ICT, given that I chose to present our most recent Bayesian adversarial privacy paper. Hence, I stood within a game-theoretic, Bayesian, formal landscape, presumably loosing most of the audience and keeping them away from their lunch!
Other speakers included Simon Lucas from Queen Mary London on Simulation-based AI, which I had trouble distinguishing from building a statistical model by goodness of fit (and using bandits used for update), while focussing on competing on some computer game challenges. And Volker Tresp from LMU München on a tensor brain model that he opposes to a Bayesian brain (with a related paper entitled Bayes or Heisenberg: Who(se) rules? which we discussed in general terms over lunch, namely Bayesian learning vs. quantum updating. And Michal Valko from INRIA Paris (and other companies), who went full blast against the Bradley-Terry model!, with a title of Nash and Nemirovski walk into a bar! With a half-time technique approximating Nash equilibria that reminded me of leapfrog. Much entertaining talk that further provided a game-theoretic transition to mine’s.
As an aside, I played yesterday with ChatGPT composing my talk slides out of our arXiv document and it proved a disaster, with hallucinations of results and concepts not in the paper and a complete mess of handling graphs, first creating generic, fake, unrelated pictures, then inserting actual graphs haphazardly throughout the slides. The sorry result I obviously did not use as the workshop did not seem the ideal place for this sort of prank! The actual version only recycles a few of its summarising slides. (With ye Norse farce proper colour choice!)




![As I am (slowly) recovering from my hamstring injury of past Xmas, I entered the half-marathon race of the Greater Paris I had booked months ago, as the distance seemed within reach. Not expecting a great time. The route was impractical, from reaching the horse-track of Bois de Vincenne on the very day EU switches to CEST, with train shortages on both RER A and B, to running on bike paths, sidewalks, and canal paved decks, within a dense crowd. With very few Paris highlights beyond the 11th arrondissement City Hall and the finish on [a completely empty] Stade de France. Only perks were the start with a horse pulling a sulky and playing the hare, the cold windless rainless weather, and a pace runner at 1:30, whom I kept in sight for the whole race. Hence rather glad with the outcome. On the way to the train station, far from the official village, I came across a scientology tent offering... massages, a very first for me! As a minor inconvenience, my bib got mixed up with the bib of one of my students, which simply means my second position in the M5M group did not get recorded. Fortunately, she (I) just missed the 10th position on the female scratch podium, which would have deprived the actual 10th runner of her win!](https://i0.wp.com/xianblog.fr/wp-content/uploads/2025/03/granpari25.png?resize=450%2C356&ssl=1)
