The BayesComp MCMski V [or MCMskv for short] has now its official website, once again maintained by Merrill Lietchy from Drexel University, Philadelphia, and registration is even open! The call for contributed sessions is now over, while the call for posters remains open until the very end. The novelty from the previous post is that there will be a “Breaking news” [in-between the Late news sessions at JSM and the crash poster talks at machine-learning conferences] session to highlight major advances among poster submissions. And that there will be an opening talk by Steve [the Bayesian] Scott on the 4th, about the frightening prospect of MCMC death!, followed by a round-table and a welcome reception, sponsored by the Swiss Supercomputing Centre. Hence the change in dates. Which still allows for arrivals in Zürich on the January 4th [be with you].

Following the highly successful [authorised opinion!, from objective sources] MCMski IV, in Chamonix last year, the BayesComp section of ISBA has decided in favour of a two-year period, which means the great item of news that next year we will meet again for MCMski V [or MCMskv for short], this time on the snowy slopes of the Swiss town of Lenzerheide, south of Zürich. The committees are headed by the indefatigable Antonietta Mira and Mark Girolami. The plenary speakers have already been contacted and Steve Scott (Google), Steve Fienberg (CMU), David Dunson (Duke), Krys Latuszynski (Warwick), and Tony Lelièvre (Mines, Paris), have agreed to talk. Similarly, the nine invited sessions have been selected and will include Hamiltonian Monte Carlo, Algorithms for Intractable Problems (ABC included!), Theory of (Ultra)High-Dimensional Bayesian Computation, Bayesian NonParametrics, Bayesian Econometrics, Quasi Monte Carlo, Statistics of Deep Learning, Uncertainty Quantification in Mathematical Models, and Biostatistics. There will be afternoon tutorials, including a practical session from the Stan team, tutorials for which call is open, poster sessions, a conference dinner at which we will be entertained by the unstoppable Imposteriors. The Richard Tweedie ski race is back as well, with a pair of Blossom skis for the winner!
I just learned that a micro-brew brand of homemade skis has connections with statistics and, who knows, could become a sponsor to the next MCMSki… Indeed, the brand is called deviation (as in standard deviation), located in Gresham, Oregon, and sell locally made skis and snowboards with names like The Moment Generator or The Mode! The logo clearly indicates a statistical connection:
As it happens, two of the founding partners of deviation, Tim and Peter Wells, are the sons of my long-time friend Marty Wells from Cornell University. When I first met them, they were great kids, young enough to give no inkling they would end up producing beautiful hardwood core skis in a suburb of Portland, Oregon!!! Best wishes to them and to deviation, the most statistical of all ski brands! (Here is a report in The Oregonian that tells the story of how deviation was created.)
[Here is a call from the BayesComp Board for proposals for MCMSki 5, renamed as below to fit the BayesComp section. The earlier poll on the ‘Og helped shape the proposal, with the year, 2016 vs. 2017, remaining open. I just added town to resort below as it did not sound from the poll people were terribly interested in resorts.]
The Bayesian Computation Section of ISBA is soliciting proposals to host its flagship conference:
Bayesian Computing at MCMSki
The expectation is that the meeting will be held in January 2016, but the committee will consider proposals for other times through January 2017.
This meeting will be the next incarnation of the popular MCMSki series that addresses recent advances in the theory and application of Bayesian computational methods such as MCMC, all in the context of a world-class ski resort/town. While past meetings have taken place in the Alps and the Rocky Mountains, we encourage applications from any venue that could support MCMSki. A three-day meeting is planned, perhaps with an additional day or two of satellite meetings and/or short courses.
One page proposals should address feasibility of hosting the meeting including
1. Proposed dates.
2. Transportation for international participants (both the proximity of international airports and transportation to/from the venue).
3. The conference facilities.
4. The availability and cost of hotels, including low cost options.
5. The proposed local organizing committee and their collective experience organizing international meetings.
6. Expected or promised contributions from the host organization, host country, or industrial partners towards the cost of running the meetings.
Proposals should be submitted to David van Dyk (dvandyk, BayesComp Program Chair) at imperial.ac.uk no later than May 31, 2014.
The Board of Bayesian Computing Section will evaluate the proposals, choose a venue, and appoint the Program Committee for Bayesian Computing at MCMSki.
Along other members of BayesComp who launched a brainstorming session for the next MCMSki meeting before the snow has completely melted from our skis, we discussed the following topics about the future meeting:
1. Should we keep the brandname MCMSki for the incoming meetings? The argument for changing the name is that the community is broader than MCMC, as already shown by the program of MCMCSki 4. I have no strong feeling about this name, even though I find it catchy and sexy! I would thus rather keep MCMSki because it is already a brandname. Else, we could switch to M(CM)Ski, MCMSki with friends (and foes?), Snowtistics and Compuskis, or to any other short name with or without ski in it, as long as the filiation from the previous meetings is clear in the mind of the participants.
2. Should we move the frequency to two years? While the current meeting was highly popular and attracted the record number of 223 participants, and while the period right after the Winter break is not so heavily packed with meetings, we were several at a banquet table last week to object to a planned move from three to two years. I understand the appeal of meetings with great speakers in a terrific mountainous taking place as often as possible… However what stroke me with the meeting last week is that, despite the large number of parallel sessions, I overwhelmingly heard novel stuff, compared with previous meetings. And would have heard even more, had I been gifted with ubiquity. Moving to two years could cull this feeling. And induce “meeting fatigue. Furthermore, I fear that the increase in ISBA sections and the natural increase of meeting entropy pushes the percentage of meetings one can attend down and down. Sticking to a three year period would keep MCMSki more significantly attractive in that refusing an invitation would mean postponing for three years, &tc. So I personally oppose a move to two years.
3. Should we seek further financial support? The financial support behind a conference is obviously crucial. When planning MCMski 4, I however decided against contacting companies as I have no skills in the matter, but finding ways to support conference rooms, youngster travels, ski race, poster prizes and banquet would be more-than-nice. Anto’s initiative to bring a pair of skis offered by a ski company was a great one and one feat that I hope can be duplicated in the future. (During my spare week in Chamonix, I contacted ski rentals and the skipass company for a rebate, to no avail.) Travel support from ISBA and SBSS towards the travel costs of around 20 young researchers was much appreciated but is not necessarily to be found at each occurrence… Note that, despite the lack of corporate support, MCMski 4 is going to provide a positive financial return to ISBA (and BayesComp) and I strongly suggest we keep a tradition of minimalist services for the future meetings in order to fight outrageous conference fees. I think the fees should cover the conference rooms and possibly a cuppa or two a day but nothing more. In particular, the banquet should remain optional. And so should any other paying social event. (We can also do without goodies and conference material.)
4. Where should the next meeting take place? The call is on for potential organisers in either 2016 or 2017, early January. Between the Alps and the Rockies, there are plenty of possible locations, but more exotic places in the Northern Hemisphere could be suggested as well, from Lapland to Hokkaido… A question raised by Christophe Andrieu that I’d like to second is whether the preference should go to places that qualify as villages or as resort. Bormio and Chamonix are villages, while Park City is not. (I definitely prefer villages!)
Now that the conference and the Bayesian non-parametric satellite workshop (thanks to Judith!) are over, with (almost) everyone back home, and that the post-partum conference blues settles in (!), I can reflect on how things ran for those meetings and what I could have done to improve them… (Not yet considering to propose a second edition of MCMSki in Chamonix, obviously!)
Although this was clearly a side issue for most participants, the fact that the ski race did not take place still rattles me! In retrospect, adding a mere 5€ amount to the registration fees for all participants would have been enough to cover the (fairly high) fares asked by the local ski school. Late planning for the ski race led to overlook this basic fact…
Since MCMSki is now the official conference of the BayesComp section of ISBA, I should have planned well in advance a section meeting within the program, if only to discuss the structure of the next meeting and how to keep the section alive. Waiting till the end of the last section of the final day was not the best idea!
Another thing I postponed for too long was seeking some sponsors: fortunately, the O’Bayes meeting in Duke woke me up to the potential of a poster prize and re-fortunately Academic Press, CRC Press, and Springer-Verlag reacted quickly enough to have plenty of books to hand to the winners. If we could have had another group of sponsors financing a beanie or something similar, it would have been an additional perk… Even though I gathered enough support from participants about the minimalist conference “package” made of a single A4 sheet.
Last, I did not advertise properly on the webpage and at all during the meeting for the special issue of Statistics and Computing open to all presenters at MCMSki IV! We now need to send a reminder to them…
The next MCMSki meeting, MCMSki IV, will be held in Chamonix Mont-Blanc, France, from Monday, January 6 to Wednesday, January 8, 2014. As for the previous MCMSki meetings, it jointly supported by the IMS (Institute of Mathematical Statistics) and ISBA (International Society for Bayesian Analysis), as the first meeting of the newly created BayesComp section of ISBA. It will focus on all aspects of MCMC theory and methodology, including related fields like sequential Monte Carlo, approximate Bayesian computation, Hamiltonian Monte Carlo. In contrast with the earlier meetings, it will merge the satellite Adap’ski workshop into the main meeting by having parallel (invited and contributed) sessions on those different themes. A call for proposals of sessions and talks is available here. There will be also opportunities for presenting one’s work at plenary and well-attended evening poster sessions.
In terms of location, after an excursion to Utah, MCMSki IV is back in the Alps, on the French side of Mont-Blanc, and Chamonix offers a wide range of outdoor and indoor activities during the breaks, with all levels of skiing available. The meeting will take place at the Conference Centre le Majestic (Centre des Congrès – Le Majestic) in Chamonix Mont-Blanc. (With a large population of English expatriates living there, Chamonix is very easy to handle for English speakers. The lodging capacities are both diverse and plenty.)
