Read the last two volumes in The Witcher series, The Tower of Swallows and The Lady of the Lake, with some difficulty as I found them [again] overly stretched. Plus recycling a whole lot of older myths, like the Arthurian tale of The Lady of the Lake to start with. But the major battle scene in the final volume is worth reading and very cinéma-esque… And the slugguish construction of the characters’ arcs eventually make sense. If a bit too much of a happy ending imho. And I also read [much faster, mostly while in Marseille] the third book of the Eastern Bloc series by Olen Steinhauer, 36 Yalta Boulevard (the local equivalent of Lybyanka), a bit less exciting, if covering another aspect of the Eastern block countries at the time of the Czechoslovakian uprising in 1968. Less interesting because of the convoluted guilty-non-guilty scenario. Quite interesting for impersonating this time Sev,  the most ideological of the members of the detective team, for taking place in Vienna part of the time. Less realistic because by rendering Sev so realistically human and compelling, his blind adhesion to the Party line does not make sense, the more when exposing the corruption and double game of some of his superiors.

Did not cook much in the past weeks, first for being at CIRM (with an escape to Cassis for a nice if not fabulous dinner by the harbour) and then for going through the fruit and veggies crates we bought in Aveyron on our way back home (after carrying South-East wine South-East!). Would have enjoyed tasting some boar meat at CIRM, given how prevalent the animals are on the campus (with apparently no warning for guests).

Watched Strangers 2, the second season of the Korean TV series. Which I enjoyed even more than the first one. With the central characters being the same but (appearing) older and a stronger and less broken scenario, centering on the power struggle between police and public prosecution. And less of the chaebol‘s power struggle and recurring corruption. Plus a more central and less caricaturesque role of women. It is still unclear if and when the Season 3 will happen.

ISBA 2021 grand finale

Last day of ISBA (and ISB@CIRM), or maybe half-day, since there are only five groups of sessions we can attend in Mediterranean time.

My first session was one on priors for mixtures, with 162⁺ attendees at 5:15am! (well, at 11:15 Wien or Marseille time), Gertrud Malsiner-Walli distinguishing between priors on number of components [in the model] vs number of clusters [in the data], with a minor question of mine whether or not a “prior” is appropriate for a data-dependent quantity. And Deborah Dunkel presenting [very early in the US!] anchor models for fighting label switching, which reminded me of the talk she gave at the mixture session of JSM 2018 in Vancouver. (With extensions to consistency and mixtures of regression.) And Clara Grazian debating on objective priors for the number of components in a mixture [in the Sydney evening], using loss functions to build these. Overall it seems there were many talks on mixtures and clustering this year.

After the lunch break, when several ISB@CIRM were about to leave, we ran the Objective Bayes contributed session, which actually included several Stein-like minimaxity talks. Plus one by Théo Moins from the patio of CIRM, with ciccadas in the background. Incredibly chaired by my friend Gonzalo, who had a question at the ready for each and every speaker! And then the Savage Awards II session. Which ceremony is postponed till Montréal next year. And which nominees are uniformly impressive!!! The winner will only be announced in September, via the ISBA Bulletin. Missing the ISBA general assembly for a dinner in Cassis. And being back for the Bayesian optimisation session.

I would have expected more talks at the boundary of BS & ML (as well as COVID and epidemic decision making), the dearth of which should be a cause for concern if researchers at this boundary do not prioritise ISBA meetings over more generic meetings like NeurIPS… (An exception was George Papamakarios’ talk on variational autoencoders in the Savage Awards II session.)

Many many thanks to the group of students at UConn involved in setting most of the Whova site and running the support throughout the conference. It indeed went on very smoothly and provided a worthwhile substitute for the 100% on-site version. Actually, I both hope for the COVID pandemic (or at least the restrictions attached to it) to abate and for the hybrid structure of meetings to stay, along with the multiplication of mirror workshops. Being together is essential to the DNA of conferences, but travelling to a single location is not so desirable, for many reasons. Looking for ISBA 2022, a year from now, either in Montréal, Québec, or in one of the mirror sites!
