Here we go! We have just completed the webpage for the BayesComp 2027 mirror conference in Aussois, French Alps, and launched the call for contributions.

This meeting mirrors the main BayesComp 2027 conference, held in Texas on the same week. As such, it will broadcast live and delayed sessions from the main conference, including plenary sessions, host local talk and poster sessions (to be broadcasted), and more generally provide an alternative forum for researchers in Bayesian computational statistics who cannot attend BayesComp 2027. As discussed earlier on the ‘Og, and following a debate launched at the ISBA 2024 World Meeting in Venezia, ISBA is now considering mirror (or multi-hub) meetings as a possible way to address accessibility, sustainability, and inclusiveness issues in its scientific meetings. 

The scientific committee will select presentations soon after the submission deadline, on 30 November 2026. Note that due to the capacity of the CAES Paul Langevin conference centre in Aussois the number of participants will be capped at 200. (Travel to Aussois by train to Modane is easy, thanks to direct, fast trains from Paris (4h), Torino (1h), and Lyon (2h). And by car if need be, since Modane is the French exit of the Tunnel du Fréjus (aka Traforo Alpino del Fréjus) linking France and Italy, the Italian exit being Bardonecchia.)

persuasive (and Oceanic) privacy

I am quite excited about the paper James Baillie, Joshua Bon, Judith Rousseau, and myself just arXived! A novel framework for measuring privacy we have been working on for at least the past year, partly through the previous Les Houches privacy workshops. In the spirit of these workshops and the larger scale ERC Synergy grant OCEAN, we develop therein a rather generic Bayesian game-theoretic perspective on achieving statistical privacy. It involves a Sender (observing the original data and delivering a limited output) and a Receiver (with potential adversarial intentions). The paper mostly focus on setting a theoretical framework, including the creation of new, purpose-driven privacy definitions that are rigorously justified, while also allowing for the assessment of existing privacy guarantees through game theory. While this was not our original intent, we show that pure and probabilistic differential privacy notions, in the Dwork et al. (2006) sense, are special cases of our framework. This setting provides new interpretations of the post-processing inequality. Furthermore, and somewhat more importantly, we also prove that our privacy guarantees can be established for deterministic algorithms, which are outside current privacy standards. Hopefully, we’ll make further progress at the incoming privacy workshop next month, to be held in Venice (again).

Nature on mirror conferences

In a news article entitled “Scientists skip key US meetings — and seize on smaller alternatives”, Nature discusses the impact of the restrictive policies put in place by the Trump administration on US conferences and their attendance. Including the multiplication of mirror and satellite meetings. One of the examples in the article is Neurips 2025,

“…the artificial-intelligence conference NeurIPS hosted not only its main meeting in San Diego, California, but also its first-ever alternative location, in Mexico City, with the goal of alleviating travel challenges (…) in response to “skyrocketing attendance and difficulties in obtaining travel visas some attendees have experienced in the past few years when only one location was available” [while] a group of AI researchers in Europe organized an independent spin-off conference, dubbed EurIPS, in Copenhagen (…) owing to concerns including climate change [and people expressing] a desire for a less hostile environment”

With a limited number of 500 participants attending in Mexico. And a massive number in Copenhagen, over 2,000! With a final quote from Emtiyaz Khan (a plenary speaker at ISBA 2026):

“[I] chose to travel to EurIPS rather than NeurIPS because of the difficulties many others faced in getting into the United States. The smaller nature of EurIPS made it much easier to meet and interact with other scientists. I absolutely loved it and I would love to see it happen again.”

This state of affairs is not going to vanish with Trump adding more countries to the banned country list, 75 at this stage!, and this is a call to arms for ISBA and IMS conference organisers towards planning for multi-hub configurations, since such international organisations cannot exclude a third of the countries in the World from attending their conferences. Which makes our current ISBA survey all the more relevant! I am currently building a mirror meeting for BayesComp 2027 in Aussois, French Alps. For those who cannot or do not wish to travel to Texas for the main conference.
