Pleased to broadcast the JSM session dedicated to the 2020 Savage Award, taking place today at 13:00 ET (17:00 GMT), with two of the Savage nominees being former OxWaSP students (and Warwick PhD students). For those who have not registered for JSM, the talks are also available on Bayeslab. (As it happens, I was also a member of the committee this year, but do not think this could be deemed a CoI!)

ABC in Svalbard [news #1]

Posted in Mountains, pictures, Running, Statistics, Travel, University life with tags , , , , , , , , , , , , , , , , , , , , on March 23, 2020 by xi'an

We [Julien and myself] are quite pleased to announce that

  • the scientific committee for the workshop has been gathered
  • the webpage for the workshop is now on-line (with a wonderful walrus picture whose author we alas cannot identify)
  • the workshop is now endorsed by both IMS and ISBA, which will handle registration (to open soon)
  • the reservation of hotel rooms will be handled by Hurtigruten Svalbard through the above webpage (this is important as we already paid deposit for a certain number of rooms)
  • we are definitely seeking both sponsors and organisers of mirror workshops in more populated locations

As an item of trivia, let me recall that Svalbard stands for the archipelago, while Spitsbergen is the name of the main island, where Longyearbyen is located. (In Icelandic, Svalbarði means cold rim or cold coast.)

ISBA in Kunming postponed till 2021

Posted in Statistics with tags , , , , , , , , , , on February 22, 2020 by xi'an

The ISBA Program committee has just announced that the ISBA World Meeting 2020 in Kunming, China, is postponed until 2021, 28 June till 03 July (and the resolution of the nCoV epidemics). Which is quite unfortunate given the closeness of the meeting and the degree of preparation of the local and scientific committees, but also unavoidable given the difficulties and reluctance of traveling to China at the moment. Hopefully, the health threat will get under control (other than keeping every citizen under lock) sooner than that. Satellite meetings like BAYSM will be moved as well, in a place and on a date soon to be announced.

As an aside, I still call for the additional organisation of mirror conferences of this World meeting  to multiply the opportunities for gathering Bayesians, share results, listen to talks and decrease the amount of travelling (and potential issues with visa, funds, human right concerns, &tc.) To quote Chairman Mao, let a hundred flowers bloom, let a hundred schools of thought contend!

new news about ISBA2020

Posted in pictures, Statistics, Travel with tags , , , , , , on January 29, 2020 by xi'an

Dear ISBA Members,

As you probably are all aware now that there is a coronavirus epidemic going around in China, impacting most severely Hubei province but all provinces in China have been affected to various extents. Expectedly there are concerns among the community regarding attending the ISBA World Meeting in China in late June.

We are keeping a close eye on the development. While at this point we are cautiously optimistic that the epidemic will not last till June, both as a result of the extraordinary measure that China is taking to contain the spread, and as cold-like coronaviruses generally don’t spread effectively as temperature rises in spring. However, we want to stay cautious and keep options open, and will take the necessary actions to ensure the health and safety of our community.

As of now, after discussing with the ISBA executives and the local organizers, we have decided to

1. Extend the Early Registration Deadline from April 15 to May 15, allowing the prospective participants to have more time to observe the development.

2. Keep the submission for Contributed Posters open till the new Early Registration Deadline May 15.

3. Keep you all updated should there be any changes in the plan of the meeting. In particular, if in the next couple of months the epidemic is not contained, and thus there will be health risk to the community in participating in the meeting, we will consider alternatives such as postponing the World Meeting.

If you were considering submitting a Contributed Talk and/or Travel award application by the deadline Jan 31, please still do so as the Scientific Committee will need sufficient time to evaluate those submissions.

Thank you all again for your support to the meeting and ISBA.

We hope that the epidemic will be contained quickly and we will still be able to see you all in Kunming!

Best Regards,
Li Ma, on behalf of the ISBA2020 Scientific Committee

ABC in Grenoble, 19-20 March 2020 [registration open]

Posted in Mountains, Statistics, Travel, University life with tags , , , , , , , , , , , , , , on January 7, 2020 by xi'an

Reminding readers that the next occurrence of the “ABC in…” workshops will very soon take place in Grenoble, France, on 19-20 March 2020. Confirmed speakers and sessions (with more to come) are

Misspecified models

Links with Machine Learning

  • Flora Jay (Université d’Orsay, France) TBA
  • Pierre-Alexandre Mattei (Inria Sophia Antipolis – Méditerranée, France) Partially Exchangeable Networks and Architectures for Learning Summary Statistics in Approximate Bayesian Computation
  • Dennis Prangle (Newcastle University, UK) Scalable approximate inference for state space models with normalising flows

As in most earlier versions of the “ABC in…”workshops (ABC in Paris, London, Roma, &tc.), we are aiming at a workshop atmosphere and, thanks to local sponsors, the registration fees are null, but registration is compulsory. And now open!

I also remind ‘Og’s readers that Grenoble can be easily reached by fast trains from Paris, Roissy, Geneva and Lyon. (There are also flights to Grenoble airport from Warwick, as well as Bristol, Edinburgh, London, Manchester, Rotterdam, Stockholm, Warsaw, but this is less convenient than flying to Lyon Saint-Exupery airport and then catching a direct train at the airport.) To add to the appeal of the place, the workshop occurs during the skiing season, with three mountain ranges in the close vicinity. Making ABski a genuine possibility for the weekend after!
