 Last week, I got COVID for the very first (detected) time! Although it took a while to realise this was COVID and not the common cold. It started with an overnight runny nose that I attributed to swimming outside the previous and cool morn, a minor temperature shock compared with the previous week in Guadeloupe. And did not spot the unusually high heart rate that night… The next afternoon, I was feeling a bit feverish (with no fever!) and definitely tired, but again attributed the feeling to faster bike rides to and from Paris Dauphine and the after-effect of Caribean jetlag. I then had a very long night and definitely felt okay the morning after (with nightly heart rate back to normal). It is only when my wife starting showing the same symptoms that I suspected more than a common cold. With confirmation from a COVID test two days later. By then I had unfortunately contaminated a few other people,  all of whom recovered reasonably fast (phew!). I have since taken back to wear a face mask in any close encounter and warned my students. I wonder if I got it in the plane back or at Dauphine on the opening day. Definitely planning the continuation of my yearly vaccine next November!!!

MCMSki IV [day 1.5]

ridge2The afternoon sessions I attended were “Computational and Methodological Challenges in evidence synthesis and multi-step” organised by Nicky Best and Sylvia Richardson and “Approximate inference” put together by Dan Simpson. Since both Nicky and Sylvia were alas unable to attend MCMSki, I chaired their session, which I found most interesting as connected to a recurrent questioning of mine about conducting inference with partial likelihoods. Chris Paciorek also introduced a new software, Nimble, that he is currently developing.  There will be a round table on Wednesday on MCMC related software, after the ski race, so will wait till then before commenting on my reticence to engage into new softwares like Stan or Nimble… Dan’s session was also closely related with my interests, esp. Nicolas Chopin talking about quasi-Monte-Carlo versions of SMC and Clare McGrory mixing variational Bayes and sequential Monte-Carlo. In the setting of mixtures, Clare mentioned using variational Bayes as a way of estimating the number of components, which somewhat surprises me in a sequential framework because it is likely to underestimate the true number…

The poster session was successful, I think, even though a growing fever (from a cold caught on a freezing lift on Sunday!) prevented me from appreciating it fully. As usual, I wish I had had more time to discuss with all of the 35 poster presenters. (I still enjoyed very much discussing ABC at length with Jukka Corander and his students. And seeing some of my PhD students giving their first poster ever. While managing to cook a decent scallop risotto in the dinner break.) Any contribution of  a guest post on the poster sessions is most welcome!

Overall, a very full day (which ended up to late to include this part in the summary of my sessions). With very few cancellations due to the bad weather. And a very enjoyable setting in the Majestic (former) palace! Incidentally, it seems like the periphrase “French side of the Italian Alps” Antonietta Mira used for the first announcement of the conference is getting into a recurrent joke, with new variants (“Swiss side of the Italian Alps”, &tc.)
