After another absurdly early run along the Sendai River, in higher humidity than yesterday, I had plenty of time to have breakfast and commute to the conference centre for our privacy section. (“Ours” since I organised and chaired the session, but also all speakers were related with our ERC OCEAN project.) With talks by Antoine Luciano (Dauphine), Shenggang Hu (Warwick) and Joshua Bon (formerly Dauphine), Shenggang presenting his work with Gareth on calibrating a DP, noisy, unbiased, version of Metropolis-Hastings. Given the other sessions highly competing with ours, this 100% OCEAN session was well-attended! My second morning session was the theory & method part of the Savage Award, with unfortunately two of the speakers stuck in the US for visa issues and presenting remotely. There have been years where this session suffered from competition from parallel sessions, but this time showed a quite decent attendance.

As most members of the scientific committee of the BayesComp mirror in Aussois were present, we went out for lunch at a nearby hitsumabushi restaurant to plan registrations and local sessions. Which proved very productive despite enjoying the fantastic eel dishes! If making me miss the beginning of the afternoon session… and then the whole session as the room on predictive Bayes was packed (and some speakers had already delivered on the Isle of Skye). I managed to get to Bottond Szabo’s Foundation lecture, with again common threads with Skye, and then returned to my rental as I was quickly crashing…

Nature on ERC funding

Posted in Books, University life with tags , , , , , , , , , , , , , , , , , , , on June 8, 2026 by xi'an

In four recent opinion articles, Nature questions the response of the European Research Council (ERC) to a steep increase in grant applications supported by AI tools, namely Responses to the AI grant flood must prioritize fairness as part of excellence, Prestigious European science funder scraps stricter rules after researcher backlash, Could agentic AI topple grant-funding systems?, and European funder must increase capacity to meet the ambition of scientists,

What is happening is that LLMs are making the construction and design of grant applications much easier, even improving their scientific worth in many cases. Hence seeing the number of submitted proposals rise. For instance, an 142% for EU Marie Skłodowska-Curie Actions fellowships. This is getting worse with agentic AI. The funding bodies are unable to implement the various bans they set against relying on these agents. The low-tech solution of increasing the role of interviews and team assessments, while worthwhile, is not working above a certain threshold, being time-intensive (and open to many biases). A comment of 27 April 2026 suggests burning all bridges and resorting to locally designed agentic AIs to assess these proposals… As if the well-studied drawbacks of AIs and LLMs relying on black-box, biased, bibliometric, unsecured, machines would magically vanish with this new construct! The mention of post hoc human verification is also wishful thinking, considering the impact of earlier bibliometric tools such as the h-factor. (Even more recent proposals are similarly bananas.)

An editorial of 05 May 2026 claims the higher moral ground by calling for fairness and inclusivity. But with a bounded budget and an equally bounded pool of human reviewers, the protocol of evaluating an ever-growing pile of applications cannot remain the same. The ERC step of limiting how many grants researchers can apply for and how long unsuccessful candidates have to wait before they can re-apply has been rescinded under protest from some researchers. But a call of 01 May 2026 for more structural investment does not stand the test of reality. Working in an ERC panel is time-consuming, equivalent to one month of investment, and finding more willing experts is unlikely to succeed, not mentioning the rise in the ERC budget the EU Commission is not going to vote, the more (or the less!) with the rise of populist fractions in the European Parliament

Bayesian, adversarial, oceanic, privacy

We just arXived a new paper on Bayesian privacy! We meaning Cameron Bell, Antoine Luciano, Timothy Johnston and myself, as members of my ERC OCEAN lab at PariSanté and Paris Dauphine. While sharing the same ground as my recent paper with James Bailie, Joshua Bon and Judith Rousseau, this one is definitely more mainstream Bayesian in that the entire decision process falls under the Bayesian hat, with the ultimate decision being the choice of the release mechanism by the data holder (or hoarder!). To rationalise this decision process, we break the framework as resulting from the actions of three actors, namely the data holder, Alice, the data scientist, Bob, and the eavesdropper. Eve. (As in my earlier posts on solving Le Monde’s math puzzles, we could have used pronouns from other cultures, but I feared this would have confused some of the readers. Incidentally, I found out that the earliest use of the first two pronouns was within the groundbreaking cryptography 1977 paper of Rivest, Shamir and Adleman, bringing the RSA algorithm to the World! With Eve appearing in an early, highly-cited privacy paper by Montréal’s Bennett, Brassard, and (unconnected to me!) Robert, in 1988.)

We thus consider a Bayesian setting in which, given data x, held by Alice, inference is to be performed by Bob on a parameter θ. Performing such inference requires Alice releasing information derived from x, which may contain sensitive content, exploited by Eve. Our approach is to compare Alice’s release mechanisms according to both the quality of inference on θ (from Bob’s viewpoint) and the privacy leakage regarding x (sought by Eve and dreaded by Alice). To formalise this evaluation, we posit that Alice refers to a loss function that is a linear combination of Bob’s and Eve’s losses, the weight on Eve’s loss being then negative. (An alternative to be considered in future work is Alice using a ratio of Bob’s and Eve’s losses, possibly set to different powers, the rationale being that a zero loss for Eve is intolerable for Alice.) As in Bayesian experimental design, a prior on the data is necessary for Eve to infer on the hidden data based on the release mechanism and released output and for Alice to evaluate the risk of said release mechanism . (They may differ, as long as they are both made public.) To calibrate Alice’s loss, we opted for a balance that returns the same risk for a full data release and a total lack of release. In specific, informed, settings, other weights could be chosen. While finding the optimal release strategy is impossible but for highly discrete settings, the framework obviously allows for the ranking of natural strategies like insufficient statistics and synthetic datasets. Comments welcome!

ERC Starting Grants 2025

Last week, the ERC announced the winners of the Starting Grant campaign for 2025.  Congrats to all recipients!

I am no longer a member of the PE1 (maths & data sciences) panel, hence did not contribute in the least to this selection. I noticed very few statistics and data science in the list (albeit obviously not hinting at any correlation with the previous sentence!), except for a project on computational stats. There is neither no one from my departments, even tough Warwick received one grant, nor from my research circles. The re-emergence of the UK as a strong proponent among the nations submitting projects is clear, while Italian candidates remain highly successful (incl. Bocconi!).

Since the EU States did not manage to unanimously agree on suspending the Article 2 of the EU-Israel Association Agreement last summer, despite Israel’s breach of human rights on the Gaza strip, there are also ten Israeli projects supported by EU on this round. (Unless the latest announcement of further sanctions by President Ursula von der Leyen suspending bilateral support to Israel does cover this financing.)
