Bayes 250th versus Bayes 2.5.0.

Posted in Books, Statistics, Travel, University life with tags , , , , , , , , , , , , , , , , , on July 20, 2013 by xi'an

More than a year ago Michael Sørensen (2013 EMS Chair) and Fabrizzio Ruggeri (then ISBA President) kindly offered me to deliver the memorial lecture on Thomas Bayes at the 2013 European Meeting of Statisticians, which takes place in Budapest today and the following week. I gladly accepted, although with some worries at having to cover a much wider range of the field rather than my own research topic. And then set to work on the slides in the past week, borrowing from my most “historical” lectures on Jeffreys and Keynes, my reply to Spanos, as well as getting a little help from my nonparametric friends (yes, I do have nonparametric friends!). Here is the result, providing a partial (meaning both incomplete and biased) vision of the field.

Since my talk is on Thursday, and because the talk is sponsored by ISBA, hence representing its members, please feel free to comment and suggest changes or additions as I can still incorporate them into the slides… (Warning, I purposefully kept some slides out to preserve the most surprising entry for the talk on Thursday!)

R.I.P. Emile…

IMG_0272I was thus in Montpellier for a few days, working with Jean-Michel Marin and attending the very final meeting of our ANR research group called Emile…  The very same group that introduced us to ABC in 2005. We had a great time, discussing about DIYABC.2, ABC for SNPs, and other extensions with our friend Arnaud Estoup, enjoying an outdoor dinner on the slopes of Pic Saint-Loup and a wine tasting on the way there, listening to ecological modelling this morning from elephant tracking [using INLA] to shell decoration in snails [using massive MCMC], running around Crès lake in the warm rain, and barely escaping the Tour de France on my way to the airport!!!IMG_0274

latent Gaussian model workshop in Reykjavik

Posted in Mountains, R, Statistics, Travel, University life with tags , , , , on March 29, 2013 by xi'an

An announcement for an Icelandic meeting next September, meeting I would have loved to attend (darn!)… This meeting is sponsored by the BayesComp session, of course!!!

We are pleased to announce that the University of Iceland will host the 3rd Workshop on Bayesian Inference for Latent Gaussian Models with Applications (LGM).

The workshop will be held in Reykjavik, Iceland, on September 12-14 2013 at Harpa ~V Reykjavik Concert Hall and Conference Centre:

The emphasized topics of LGM 2013 are:
-Machine learning
-Spatial and spatio-temporal modeling
-Bayesian non-parametrics
-Latent Gaussian models
-The workshop is not restricted to these topics

The invited speakers are:
-Matthias Katzfuß at Universität Heidelberg
-Bani Mallick at Texas A&M University
-Peter Müller at University of Texas
-Michèle Sebag at INRIA Saclay, CNRS
-Matthias Seeger at École Polytechnique Fédérale de Lausanne
-Christopher Wikle at University of Missouri

Registration fees:
Early bird fee before May 21th ~@ 375
Registration fee after May 21th ~@ 440
Student fee ~@ 250

Detailed information on the scientific program, conference field trip, organizing committee, scientific committee and meeting registration is available on the conference web-site:

LGM 2012, Trondheim

Posted in Mountains, pictures, Running, Statistics, Travel, University life with tags , , , , , on May 31, 2012 by xi'an

A break from the “snapshots from Guérande” that will be a relief for all ‘ Og readers, I am sure: I am now in Trondheim, Norway, for the second Latent Gaussian model meeting, organised by Håvard Rue and his collaborators. As in the earlier edition in Zürich, the main approach to those models (that is adopted in the talks) is the INLA methodology of Rue, Martino and Chopin. I nonetheless (given the theme) gave a presentation on Rao-Blackwellisation techniques for MCMC algorithms. As I had not printed the program of the meeting prior to my departure (blame Guérande!), I had not realised I had only 20 minutes for my talk and kept adding remarks and slides during the flight from Amsterdam to Trondheim [where the clouds prevented me from seeing Jotunheimen]. (So I had to cut the second half of the talk below on parallelisation. Even with this cut, the 20 minutes went awfully fast!) Apart from my talk, I am afraid I was not in a sufficient state of awareness [due to a really early start] to give a comprehensive of the afternoon talks….

Trondheim is a nice city that sometimes feels like a village despite its size. Walking up to the university along typical wooden houses, then going around the town and along the river tonight while running a 10k loop left me with the impression of a very pleasant place (at least in the summer months).
