Saffron and Brimstone [book review]

Posted in Books, Kids, Travel with tags , , , , , , , , on August 15, 2015 by xi'an

I cannot really remember how I came across this book, when selecting Amazon (free) books to collect from Andrew on my last trip to New York… (Thanks to ‘Og readers!) Presumably the name popped out of a list of recommended books. The cover was intriguing enough to stop by and to spot that the author was Elizabeth Hand, whose horror/fantasy trilogy I had liked very much in the late 80’s… So I ordered the book and brought it back from New York. Only to realise that this was an altogether different Elizabeth Hand, whose book Available Dark I had read a little while ago. And did not like so much. However, since the book is a collection of short and less short stories, I gave it a try.

As it happens, this Saffron and Brimstone truly is a great collection of short stories, fantastic in a completely different frame than those of the fantasy books I usually review here. It is a fantastic that borders reality, sometimes hardly fantastic, but with a constant feeling of something being not fully natural, not completely normal. The subtitle of “strange stories” is quite pertinent, as the feeling of strangeness hits the reader (or this reader) almost instantaneously from the beginning of each story. I enjoyed all of the eight stories for different reasons, from a reminiscence of an “Alfred Hitchcock presents” short story called the Cocoon that terrified me [as a pre-teen] when I read it late at night!, to variations around Greek myths that brings them beautifully into the modern era. And always with a central female character who brings another degree of strangeness and surreality to the tale.  I do not think it matters the least that those novels are or are not fantasy or fantastic. They are simply gems of contemporary literature. Superb. (Which makes the rather unexceptional Available Dark the more inexplicable!)

Paris Machine Learning Meeting #10 Season 2

Invalides, Paris, May 8, 2012

Tonight, I am invited to give a speed-presenting talk at the Paris Machine Learning last meeting of Season 2, with the themes of DL, Recovering Robots, Vowpal Wabbit, Predcsis, Matlab, and Bayesian test [by yours truly!] The meeting will take place in Jussieu, Amphi 25, Here are my slides for the meeting:

As it happened, the meeting  was quite crowded with talks and plagued with technical difficulties in transmitting talks from Berlin and Toronto, so I came to talk about three hours after the beginning, which was less than optimal for the most technical presentation of the evening. I actually wonder if I even managed to carry the main idea of replacing Bayes factors with posteriors of the mixture weight! [I had plenty of time to reflect upon this on my way back home as I had to wait for several and rare and crowded RER trains until one had enough room for me and my bike!]

MCqMC 2014 [closup]

Posted in pictures, Running, Statistics, Travel, University life, Wines with tags , , , , , , , on April 16, 2014 by xi'an

Leuven6As mentioned earlier, this was my very first MCqMC conference and I really enjoyed it, even though (or because) there were many topics that did not fall within my areas of interest. (By comparison, WSC is a serie of conferences too remote from those areas for my taste, as I realised in Berlin where we hardly attended any talk and hardly anyone attended my session!) Here I appreciated the exposure to different mathematical visions on Monte Carlo, without being swamped by applications as at WSC… Obviously, our own Bayesian computational community was much less represented than at, say, MCMSki! Nonetheless, I learned a lot during this conference for instance from Peter Glynn‘s fantastic talk, and I came back home with new problems and useful references [as well as a two-hour delay in the train ride from Brussels]. I also obviously enjoyed the college-town atmosphere of Leuven, the many historical landmarks  and the easily-found running routes out of the town. I am thus quite eager to attend the next MCqMC 2016 meeting (in Stanford, an added bonus!) and even vaguely toying with the idea of organising MCqMC 2018 in Monaco (depending on the return for ISBA 2016 and ISBA 2018). In any case, thanks to the scientific committee for the invitation to give a plenary lecture in Leuven and to the local committee for a perfect organisation of the meeting.

packed off!!!

La Défense, Paris, Feb. 04, 2013Deliverance!!! We have at last completed our book! Bayesian Essentials with R is off my desk! In a final nitty-gritty day of compiling and recompiling the R package bayess and the LaTeX file, we have reached versions that were in par with our expectations. The package has been submitted to CRAN (it has gone back and forth a few times, with requests to lower the computing time in the examples: each example should take less than 10s, then 5s…), then accepted by CRAN, incl. a Windows version, and the book has be sent to Springer-Verlag. This truly is a deliverance for me as this book project has been on my work horizon almost constantly for more than the past two years, led to exciting times in Luminy, Carnon and Berlin, has taken an heavy toll on my collaborations and research activities, and was slowly turning into a unsavoury chore! I am thus delighted Jean-Michel and I managed to close the door before any disastrous consequence on either the book or our friendship could develop. Bayesian Essentials with R is certainly an improvement compared with Bayesian Core, primarily by providing a direct access to the R code. We dearly hope it will attract a wider readership by reducing the mathematical requirements (even though some parts are still too involved for most undergraduates) and we will keep testing it with our own students in Montpellier and Paris over the coming months. In the meanwhile, I just enjoy this feeling of renewed freedom!!!
