Denkmal für die ermordeten Juden Europas, Berlin

WSC 2012, Berlin

For once, while being away at a conference (WSC 2012), I will not be reporting on every day and session, for the simple reason I attended very few sessions and have therefore little to report! Last year in Phoenix, I had already resented a certain difficulty to relate with most of the talks and felt it unprofitable to attend most sessions, except those organised by Pierre Lécuyer and co-authors. This year, the pervasive combination of snowed-in Berlin, of a nice rental apartment (five time cheaper than the fancy Intercontinental), shared with Jean-Michel Marin whose inputs on the book were way overdue, of the distance to the Intercontinental, and of moderately exciting sessions meant that we spent most of the conference closeted in this apartment in Schöneberg, except for a quick stroll on Unter den Linden and for the inaugural conference by Stefan Rahmstorf on climate change (whose contents were surely worth broadcasting, although mildly related with simulation), a session on rare event simulation, and the session I organised on Monte Carlo Methods in Statistics (same title as the special issue of TOMACS, not coincidentally!). Actually, the feeling was mutual, apparently!, as our session attracted very few WSC 2012 attendees, a shame when considering the three great talks delivered by Anthony Lee, Jean-Michel Marin, and Nial Friel. To wit, Anthony talked about several scenarios for running ABC (see my earlier post of yesterday), Jean-Michel explained the tolerance selection developed in our recent paper, and Nial Friel discussed an on-going project dealing with composite likelihood in Gibbs random fields, a topic obviously close to my interests and the just accepted PNAS paper!

Special Issue of ACM TOMACS on Monte Carlo Methods in Statistics

As posted here a long, long while ago, following a suggestion from the editor (and North America Cycling Champion!) Pierre Lécuyer (Université de Montréal), Arnaud Doucet (University of Oxford) and myself acted as guest editors for a special issue of ACM TOMACS on Monte Carlo Methods in Statistics. (Coincidentally, I am attending a board meeting for TOMACS tonight in Berlin!) The issue is now ready for publication (next February unless I am confused!) and made of the following papers:

* Massive parallelization of serial inference algorithms for a complex generalized linear model MARC A. SUCHARD, IVAN ZORYCH, PATRICK RYAN, DAVID MADIGAN	Abstract
*Convergence of a Particle-based Approximation of the Block Online Expectation Maximization Algorithm SYLVAIN LE CORFF and GERSENDE FORT	Abstract
* Efficient MCMC for Binomial Logit Models AGNES FUSSL, SYLVIA FRÜHWIRTH-SCHNATTER, RUDOLF FRÜHWIRTH	Abstract
* Adaptive Equi-Energy Sampler: Convergence and Illustration AMANDINE SCHRECK and GERSENDE FORT and ERIC MOULINES	Abstract
* Particle algorithms for optimization on binary spaces CHRISTIAN SCHÄFER	Abstract
* Posterior expectation of regularly paved random histograms RAAZESH SAINUDIIN, GLORIA TENG, JENNIFER HARLOW, and DOMINIC LEE	Abstract
* Small variance estimators for rare event probabilities MICHEL BRONIATOWSKI and VIRGILE CARON	Abstract
* Self-Avoiding Random Dynamics on Integer Complex Systems FIRAS HAMZE, ZIYU WANG, and NANDO DE FREITAS	Abstract
* Bayesian learning of noisy Markov decision processes SUMEETPAL S. SINGH, NICOLAS CHOPIN, and NICK WHITELEY	Abstract

Here is the draft of the editorial that will appear at the beginning of this special issue. (All faults are mine, of course!)

Reuven Rubinstein (1938-2012)

I just learned last night that Professor Reuven Rubinstein passed away. While I was not a close collaborator of him, I met Reuven Rubinstein a few times at conferences and during a short visit to Paris, and each time learned from the encounter. I also appreciated his contributions to the field of simulation, esp. his cross-entropy method that culminated in the book The Cross-Entropy Method with Dirk Kroese. Reuven was involved in many aspects of simulation along his prolific career, he will be especially remembered for his 1981 book Simulation and the Monte Carlo Method that is arguably the very first book on simulation as a Monte Carlo method. This book had a recent second edition, co-authored with Dirk Kroese as well. It is thus quite a sad day to witness this immense contributor to the field leave us. (Here is a link to his webpage at Technion, including pictures of a trip to the Gulag camp where he spent most of his childhood.) I presume there will be testimonies about his influence at the WSC 2012 conference here in Berlin.

nach Berlin! [WSC 2012]

I am off to Berlin this afternoon with Jean-Michel Marin to attend the Winter SImulation Conference (WSC 2012). I hope I can go running around the nearby Tiergarten despite the sub-zero temperatures…(I am also of course looking forward the Monte Carlo sessions of the conference. And am curious at how well attended it will be for its first trip outside North-America.)
