Read Jen Williams’ The Winnowing Flame trilogy, induced by two British Fantasy Awards associated with the first two volumes. This is quite a disappointing series, the more one goes through the story. At the start, while I found the story rather simplistic in its world building and in repeating the all-too-common pattern of a very few individuals saving the planet from a recurrent alien invasion (and even more the blob nature of said aliens!, as I am adverse to blob scenari, ever since as a teenager I wrote a terrible short story on a blob invasion!!), I appreciated the character of Vintage (!), both vigneronne and femme savante. A most unusual combination in fantasy books. However, I disliked the mix of fantasy (multiple kingdoms, swords, dragons, and a mostly primitive society) and science-fiction (spaceships, magic-driven trains). The cliffhanging final chapter of each of the volumes was rather heavily predictable and the inconsistency in the characters’ psychology a major flaw, including interminable back-and-forth between their respective feelings. And a poor ending to the trilogy due to the ever changing nature of the invasive creature(s) that survives all attempts at destruction until it doesn’t. Plus laughable mundane parts worrying about clothes and picnics while the entire world is under existential threat.

Had consecutively whitlow and singles, which gave me the opportunity to seek the English version of those viral infections. The former was possibly caused by gardening barefoot and quickly got away, while the later was a bit of a mystery, since it is not contagious (even though I cannot but relate to the fact my mother got it two weeks earlier). It got circumscribed to one eyebrow, but a general itching along the cranial nerves that has not yet vanished. Fortunately, it did not impact my running times!!

Watched Glitch, a Korean sci-fiction series, so absurd it is hilarious. Painfully slow as usual, but with a surprising ending. And the second season of The Wheel of Times, loosely following the second volume, The Great Hunt, still burdened with a kitch rendering of the WoT universe, predictable twists, caricaturesque characters (Liandrin!, Matt!) and too much inner questioning.

Advances in scalable Bayesian computation [day #4]

polyptych painting within the TransCanada Pipeline Pavilion, Banff Centre, Banff, March 21, 2012Final day of our workshop Advances in Scalable Bayesian Computation already, since tomorrow morning is an open research time ½ day! Another “perfect day in paradise”, with the Banff Centre campus covered by a fine snow blanket, still falling…, and making work in an office of BIRS a dream-like moment.

Still looking for a daily theme, parallelisation could be the right candidate, even though other talks this week went into parallelisation issues, incl. Steve’s talk yesterday. Indeed, Anthony Lee gave a talk this morning on interactive sequential Monte Carlo, where he motivated the setting by a formal parallel structure. Then, Darren Wilkinson surveyed the parallelisation issues in Monte Carlo, MCMC, SMC and ABC settings, before arguing in favour of a functional language called Scala. (Neat entries to those topics can be found on Darren’s blog.) And in the afternoon session, Sylvia Frühwirth-Schnatter exposed her approach to the (embarrassingly) parallel problem, in the spirit of Steve’s , David Dunson’s and Scott’s (a paper posted on the day I arrived in Chamonix and hence I missed!). There was plenty to learn from that talk (do not miss the Yin-Yang moment at 25 mn!), but it also helped me to break a difficulty I had with the consensus Bayes representation for two weeks (more on that later!). And, even though Marc Suchard mostly talked about flu and trees in a very pleasant and broad talk, he also had a slide on parallelisation to fit the theme! Although unrelated with parallelism,  Nicolas Chopin’s talk was on sequential quasi-Monte Carlo algorithms: while I had heard previous versions of this talk in Chamonix and BigMC, I found it full of exciting stuff. And it clearly got the room truly puzzled by this possibility, in a positive way! Similarly, Alex Lenkoski spoke about extreme rain events in Norway with no trace of parallelism, but the general idea behind the examples was to question the notion of the calibrated Bayesian (with possible connections with the cut models).

This has been a wonderful week and I am sure the participants got as much as I did from the talks and the informal exchanges. Thanks to BIRS for the sponsorship and the superb organisation of the week (and to the Banff Centre for providing such a paradisical environment). I feel very privileged to have benefited from this support, even though I deadly hope to be back in Banff within a few years.
