SEINE AI

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!)

Mythologies

Last week, we went to a dance performance, in Seine Musicale (a rehabilitation of the former grounds of the original Renault Car factory where my childhood neighbour worked in the 1920s!). Called Mythologies, and created in 2022, it was delivered by a mix of Angelin Preljocaj’s troup and the Bordeaux Opéra dancers, with the music composed by (ex-)Daft Punk, Thomas Bangalter! The show was impressive, in a physical sense since we were seated close to the stage and the speakers. The music was a rather neo-classic mix, with no punkness involved, a wee bit on the heavy side, and the dance traditional as well, while contemporary. The skill and stamina of the dancers amazed me. The different tableaux were related to Greek mythology—except for a Maya interlude that I missed—, albeit missing a story line, but rather (too?) efficient in delivering the corresponding myth. In particular, the tableaux on the labyrinth were brilliant. The epilogue is maybe the strongest moment of the show, with corpses spread all over the stage and death figures walking through. Possibly over explained but nonetheless tragically beautiful…
