sunset on the Danube, Budapest, July 23, 2013Last day at EMS 2013! I started the day with an attempt to run inside the big necropolis on the east of town (Nemzeti sirkert), attempt that failed as I was too early. I then delivered my ISBA Thomas Bayes memorial lecture, with an amazing number of people (amazing conditional on the fact that it was delivered at 9am the morning after the banquet, on the last day of the conference, that it was a memorial historical talk which could be (mis-)perceived as Bayesian propaganda, and that I had put my slides on line already!). I managed (in I hope a comprehensible and not-too-boring way!) to cover most of the slides, skipping some ABC details, in the allotted hour, and not forgetting the historical note (Teller was born here) and the local ABC picture… Many aspects of past and current Bayesian statistics were missing: Fabrizio Ruggeri pointed out prior elicitation and Xiao-Li Meng [who wore a special tie with Thomas Bayes’ picture!] George Box. As an aside, has anyone versed in image analysis ever tried to link Thomas Bayes somehow doubtful portrait with his father’s? They do not look the least related to my unexpert eyes…

The rest of the day went very quickly, with a Bayesian computation session on SMC and exact approximations, and an afternoon consisting of Larry Brown’s talk on linear models as approximations (bringing a new light on the topic!) and of Xiao-Li Meng’s talk on measuring the impact of priors through a new information device. While I attended the “Future of Statistics” panel like most of the remaining participants, the future remained rather foggy, as I could not make my mind between the optimist side pointed out the growing need of statisticians at every level and the pessimist view that those jobs were mostly taken by poorly trained non-statisticians… In conclusion, I enjoyed the meeting for its diversity and range of talks, as well as its fantastic location of course!

Here is the new version of the talk:

And I had a fairly interesting day at the conference, from Randal’s talk on hidden Markov models with finite valued observables to the two Terrys invited session (Terry Lyons vs. Terry Speed) to the machine learning session organised by a certain Michal Jordan (on the program) that turned out to be Michael Jordan (with a talk on the fusion between statistics and computability). A post-session chat with Terry Lyons also opened (to me) new perspectives on data summarisation. (And we at last managed to get a convergence result using a Rao-Blackwellisation argument!) Plus, we ended up the day in a nice bistrot called Zeller with an awfully friendly staff cooking family produces and serving fruity family wines and not yet spoiled by being ranked #1 on tripadvisor (but visibly attracting a lot of tourists like us).
