As an on-going multilevel pun (started with my misreading a famous outdoor brand logo as a Viking helmet!), and following popular request (at least from a few participants to our Bayesian school at CIRM two years ago!), I took advantage of one of the numerous make-your-own-tee websites to create a norse farce shop(pe) for afficionadas and afficionados..!

[Warning: This (silly) post is completely unrelated with the previous one!]
Last week, when biking back from ENSAE on the Plateau de Saclay, one strap of my (recent, grey, handy) North Face backpack gave way and I barely avoided a crash! The stitching at the top had unravelled, it appears, and there was no way I could fix it myself. Once safe at home, I thus called Amazon from whom I had bought it less than a year ago and was quite impressed by their handling of the matter, as they reimbursed me almost instantaneously. (Which brings the customary reminder and warning that my Amazon links are connected to my Amazon Associate account and [modest] benefits.) Anyway, this led me to concretise a pun I thought of a long while ago, namely to build a pastiche of the North Face logo where the Half-Dome representation would be turned into the half of a Viking helmet… My daughter Rachel helped me to turn this into an actual output, as shown above, but I would welcome proposals of alternative designs. The winner (if any) gets a free mug with the selected design!
ABC…ancun, July 13, 2014

We received the good news from the Program Committee of the next ISBA World meeting in Cancún, Quintana Roo, México, that our proposal of a short course on ABC methods was accepted. So, along with Jean-Michel Marin, I hope to introduce ABC to a large group of interested participants on either July 13 or the morn of July 14. Here is the abstract for the short course
ABC appeared in 1999 to solve complex genetic problems where the likelihood of the model was impossible to compute. They are now a standard tool in the statistical genetic community but have also addressed many other problems where likelihood computation was also an issue, including dynamic models in signal processing and financial data analysis. However, these methods suffer to some degree from calibration difficulties that make them rather volatile in their implementation and thus render them suspicious to the users of more traditional Monte Carlo methods. Nonetheless, ABC techniques have several claims to validity: first, they are connected with econometric methods like indirect inference. Second, they can be expressed in terms of various non-parametric estimators of the likelihood or of the posterior density and follow standard convergence patterns. At last, they appear as regular Bayesian inference over noisy data. The lectures cover those validation steps but also detail the different implementations of ABC algorithms and the calibration of their parameters. The second part of the course illustrates those issues in the special case of the coalescent model used in population genetics, where many of the early advances of ABC were first implemented.
and the complete description is available on the ISBA website.
In addition, the special ISBA section sessions for BayesComp and O’Bayes ISBA sections have been accepted too. (As well as sessions for most of the other ISBA sections.) Thanks to Raquel Prado and to the whole scientific committee for working hard towards another successful ISBA World meeting! Note that the early bird conference registration begins today, so make sure to book your seat for Cancun!
Cancun, July 14-18, 2014
Posted in Statistics, Travel, University life with tags Cancún, conference, deadline, ISBA, logo, Mexico, Valencia conferences, Yucatan on October 4, 2013 by xi'anThe next ISBA World meeting will take place in Cancún, Quintana Roo, in México. (To keep up with the Valencia meeting tradition, it is again in a resort town, after the welcome parenthesis of Kyoto 2012! I just hope the mountains are not that far…) There will be a series of short courses on July 13 (maybe including an ABC course…) and the talks will start for good on July 14. Our BayesComp and O’Bayes ISBA sections will hopefully have special invited sessions, Deadline for short courses and special sessions proposals is October 15, just like the deadlines for MCMCSki 4. (The logo is very nice, even though I do not get the meaning of the sequence 13-0-1-10-10: 13 would work for the 13th ISBA/Valencia meeting [already?!] but the other figures…!?)
Update: for some strange (Mayan?) malediction, Sophie Donnet and Michael Stumpf both tried (thanks!) to comment on that post and failed. They were both telling me that this is the date of the French National (Bastille) Day in the Maya (Long Count) calendar…. I thus got 13 completely wrong as it is read from right to left: 10th day (k’in) of the 20 day month (winal), 10th winal of the 18 months year (k’atun), first k’atun of the 20 k’atuns cycle named a b’ak’tun, final b’ak’tun of the 20 b’ak’tun cycle called piktun, and 13th piktun of the 20 piktun cycle called kalabtun… (Yes, Mayas used the base-20 count.) The calendar started on Sept. 11, in 3114 BC.
