Back in Vienna after a little bit more than a year! The opportunity was a working meeting on a CRC Handbook of mixture analysis, Sylvia Früwirth-Schnatter, Gilles Celeux and myself are editing together, along with about twenty authors, half of which also came to Vienna for the weekend. Great opportunity to all work together, towards a more coherent and comprehensive volume, as well as to enjoy the earliest stages of the Viennese winter. Very mild winter so far. I also gave a seminar Friday morning, thinking until I saw the attached poster that I was going to speak on mixtures for testing..! Except for a few seconds of uncertainty on the second version of the random forest approach, I still managed to survive the switch (in a fabulous seminar room, overlooking the Prater…) The two days meeting was very rewarding, with major changes in the contents and the goals of many chapters, including those I am contributing to.
Apart from the minor initial inconvenience that I missed my train to Brussels thanks to the SNCF train company dysfunctional automata [but managed to switch to one half-an-hour later], my Belgian trip to Louvain-la-Neuve was quite enjoyable! I met with several local faculty [UCL] members I had not seen for several years, I gave my talk for the World Statistics Day in front of a large audience, maybe not the most appropriate talk for that day since it was somewhat skeptical about the nature of statistical tests, I got sharp questions, comments, and suggestions on the mixture approach to testing [incl. a challenging one about the Bernoulli B(p) case], I had a superb and animated and friendly dinner in a local restaurant—where everyone kindly spoke French although I was the only native French speaker—, I met the next morning with two PhD students from KU Leuven (the “other” part of the former Leuven university, albeit in the Flemmish side of the border) about functional ABC and generalised Jeffreys priors, I had a few more interesting discussions, and I managed to grab a few bags of Belgian waffles in Brussels before heading home! (In case you wonder from the above pixture, the crowds in the pedestrian streets of Louvain-la-Neuve were not connected to my visit!, but to a student festival centred at
beer a 24 hour bike relay that attracted around 50,000 students, for less than a hundred bikes!)
While my train ride to the fabulous De Gaulle airport was so much delayed that I had less than ten minutes from jumping from the carriage to sitting in my plane seat, I handled the run through security and the endless corridors of the airport in the allotted time, and reached Munich in time for my afternoon seminar and several discussions that prolonged into a pleasant dinner of Wiener Schnitzel and Eisbier. This was very exciting as I met physicists and astrophysicists involved in population Monte Carlo and parallel MCMC and manageable harmonic mean estimates and intractable ABC settings (because simulating the data takes eons!). I wish the afternoon could have been longer. And while this is the third time I come to Munich, I still have not managed to see the centre of town! Or even the nearby mountains. Maybe an unsuspected consequence of the Heisenberg principle…
