A list of principles put forth by mathematicians, for mathematicians and other researchers, regarding the use of AI in research. "Number #9 will surprise you!" leidendeclaration.ai

Leiden Declaration on Artificial Intelligence and Mathematics leidendeclaration.ai
AI Weekly's analysis →
  • The Leiden Declaration, released June 2, 2026, warns AI threatens proof integrity, attribution, and peer review in mathematics.
  • Over 2,654 signatories including Fields Medal winner Terence Tao have endorsed the community-initiated declaration.
  • The International Mathematical Union backs the declaration, which makes separate recommendations to researchers, publishers, policymakers, and AI developers.

Yeah it is really a textbook example of Goodhart's law. Giving a solution to an unsolved problem is a "proxy" toward our community's understanding of the underlying mathematical structure. Solving problems is (maybe sometimes but) not often the ultimate goal. www.economist.com…

I am leading a new lab in Oxford: come join us if you don’t trust corporate AI labs to govern themselves www.robots.ox.ac.uk/~mosb/bgl/

Bayesian Governance Lab robots.ox.ac.uk
AI Weekly's analysis →
  • Oxford's Bayesian Governance Lab, led by M. A. Osborne, applies Bayesian inference, Gaussian processes and probabilistic numerics to AI assurance and governance.
  • Osborne gave oral evidence to the House of Commons Science, Innovation and Technology Committee and contributed to its interim report on twelve governance challenges.
  • Recent output includes a 2025 NeurIPS paper on human feedback valuation and a 2024 arXiv paper on compute providers as AI regulation intermediaries.

New preprint up, led by Joy (Qiping) Yang and Yash Pote, with Jonathan Scarlett: we consider a relaxation of the standard (distribution) closeness testing task, where the algo now only needs to distinguish between p=q (equal) and |H(p)-H(q)|=Ω(1) (their entropies differ). 📝 ar…

[2605.23225] Entropy Equivalence Testing arxiv.org
AI Weekly's analysis →
  • Entropy equivalence testing needs significantly fewer samples than standard closeness testing for distributions.
  • The paper delivers the first non-trivial closeness testing algorithm for low-degree Bayesian networks.
  • Matching lower bounds establish near-optimality, revealing how hard the relaxed problem is in principle.

Yifeng Chu and I just posted our paper on chaining-type bounds for expected soft maxima of Gaussian processes. The analysis makes use of a nice blend of ideas from probability, statistical physics of disordered systems, and information theory. arxiv.org/abs/2606.22611

Upper and Lower Bounds on Expected Soft Maxima of Gaussian Processes arxiv.org
AI Weekly's analysis →
  • The paper derives upper and lower bounds for soft maxima of centered Gaussian processes, defined as Gibbs averages at inverse temperature β > 0.
  • The bounds retain the same multiscale structure as generic chaining expressions, with a truncation term governed by the inverse temperature β.
  • As β → ∞, the bounds recover the majorizing measure theorem; applied to the Sherrington-Kirkpatrick model, they yield a finite-size Parisi formula.

The proceedings of ICML 2026 are online, including a position paper I took part to: proceedings.mlr.press/v306/papamar... The 29 other authors did all the work 😅 but I'm still proud to share it. Also I "officially" become a co-author of so many people I like a lot, this makes …

Position: Agentic AI Orchestration Should Be Bayes-Consistent proceedings.mlr.press
AI Weekly's analysis →
  • A 30-author ICML position paper argues Bayesian decision theory belongs in the orchestration layer of agentic AI, not inside the LLMs themselves.
  • The authors call making LLMs internally Bayesian 'computationally intensive and conceptually nontrivial as a general modeling target'.
  • They pitch calibrated beliefs and utility-aware policies for choices like which tool to call, which expert to consult, and how many resources to invest.

Theodore Papamarkou, Vladislav Smirnov, Viktor Mazanov, Artem Vazhentsev, Preslav Nakov, Timothy Baldwin, Artem Shelmanov: Bayesian control for coding agents https://arxiv.org/abs/2606.24453 https://arxiv.org/pdf/2606.24453 https://arxiv.org/html/2606.24453

Bayesian control for coding agents arxiv.org
AI Weekly's analysis →
  • A new arxiv paper recasts coding-agent orchestration as cost-sensitive sequential hypothesis testing managed by a Bayesian controller.
  • The controller decides dynamically whether to gather more evidence, refine the solution, run a verifier, or stop the run.
  • Authors report the approach is most valuable when verification is costly and critics are informative but imperfect, across six generators and nine benchmarks.

Recent commentary

"These AI companies are proving theorems as ways to advertise for their models..." Correct, but I would argue that mathematicians prove theorems to be remembered as "the guy/girl who solved this 100 years old problem", get prizes and good jobs in top universities. Not so different.
