An infinite (mixture) session was truly the first one I could attend on Day 1, as a heap of unexpected last minute issues kept me busy or on hedge for the beginning of the day (if not preventing me from a dawn dip in Calanque de Morgiou). Using the CIRM video system for zoom talked required more preparation than I had thought and we made it barely in time for the first session, while I had to store zoom links for all speakers present in Luminy. Plus allocate sessions to the rooms provided by CIRM, twice since there was a mishap with the other workshop present at CIRM. And reassuring speakers, made anxious by the absence of a clear schedule. Chairing the second ABC session was also a tense moment, from checking every speaker could connect and share slides, to ensuring they kept on schedule (and they did on both!, ta’), to checking for questions at the end. Spotting a possible connection between Takuo Mastubara’s Stein’s approximation for in the ABC setup and a related paper by Liu and Lee I had read just a few days ago. Alas, it was too early to relax as an inverter in the CIRM room burned and led to a local power failure. Fortunately this was restored prior to the mixture session! (As several boars were spotted on the campus yesternight, I hope no tragic encounter happens before the end of the meeting!!!) So the mixture session proposed new visions on infering K, the number of components, some of which reminded me of… my first talk at CIRM where I was trying to get rid of empty components at each MCMC step, albeit in a much more rudimentary way obviously. And later had the wonderful surprise of hearing Xiao-Li’s lecture start by an excerpt from Car Talk, the hilarious Sunday morning radio talk-show about the art of used car maintenance on National Public Radio (NPR) that George Casella could not miss (and where a letter he wrote them about a mistaken probability computation was mentioned!). The final session of the day was an invited ABC session I chaired (after being exfiltrated from the CIRM dinner table!) with Kate Lee, Ryan Giordano, and Julien Stoehr as speakers. Besides Julien’s talk on our Gibbs-ABC paper, both other talks shared a concern with the frequentist properties of the ABC posterior, either to be used as a control tool or as a faster assessment of the variability of the (Monte Carlo) ABC output.
It’s now official!, thanks to the support of the Société Mathématique de France (SMF), the Centre National de la Recherche Scientifique (CNRS), and the Université Aix-Marseille, we are going to have a
