In conjunction with Kerrie Mengersen’ Jean Morlet Chair at CIRM, Luminy, Marseilles, we organise a special conference “Bayesian statistics in the big data era” on November 26-30, 2018, with the following speakers having already confirmed attendance

Louis Aslett (Durham, UK)
Sudipto Banerjee (UCLA, US)
Tamara Broderick (MIT, US)
Noël Cressie (Wollongong, OZ)
Marco Cuturi (ENSAE, FR)
David Dunson (Duke, US)
Sylvia Frühwirth-Schnatter (WU, AU)
Amy Herring (Duke, US)
Gregor Kastner (WU, AU)
Ruth King (Edinburgh, UK)
Gary Koop (Edinburgh, UK)
Antonio Lijoi (Bocconi, IT)
Jean-Michel Marin (Montpellier, FR)
Antonietta Mira (Lugano, CH)
Peter Müller (UT Austin, US)
Igor Pruenster (Bocconi, IT)
Stéphane Robin (INRA, FR)
Heejung Shim (U Melbourne, OZ)
Minh-Ngoc Tran (UNSW, OZ)
Darren Wilkinson (Newcastle, UK)

(more)


Registration is free but compulsory, and we encourage all interested data scientists (and beyond) to apply and to contribute a talk or a poster. The size of the audience is limited to a maximum of 80 participants, on a first-come first-serve basis. (Cheap housing is available on the campus, located in the gorgeous national park des Calanques south of Marseilles.)


In connection with this conference, there will be a workshop the previous weekend on “Young Bayesians and Big Data for social good”, to get junior researchers interested in the analysis of data related with social issues and human rights to work with a few senior researchers. More details soon, here and on the CIRM website.

guess what..?! Yet another worskhop in the endless summer Bayesian series!

Dennis Prangle pointed to me the perfectly timed i-like workshop taking place in Newcastle, on the days priors to ABC in Edinburgh and ISBA (similarly in Edinburgh!). (Note that Warwick is also part of the i-like network. Actually, the first i-like workshop was my first trip abroad after the Accident!) I may sound negative about these workshops, but on the opposite am quite a fan of them, just regretting that the main event did not take advantage of them all to reduce the volume of talks there. As I suggested, it could have been feasible to label these satellites as part of the main conference towards making speakers at these officially speakers at ISBA 2018 in case talks were required for support…

The i-like workshop 2018 is the sixth edition of a yearly series of workshops dedicated to the topic of intractable likelihoods, hosted by Newcastle University. The workshop will take place from Wednesday 20 June 2018 – Friday 22 June 2018 in Room 2.98, Armstrong Building, Newcastle upon Tyne. Registration is free and mandatory!

I spent a few days in Newcastle at the RSS meeting of 2013, with my friends Jim Hobert and Elias Moreno. Enjoying very much the city, its surroundings, the great meadow north of the city in a glorious sunset (I still bemoan not catching on camera!). And it is just in the vicinity of Hadrian’s Wall, just on the other side of the Borders, very close to Edinburgh in fact.

bitcoin and cryptography for statistical inference and AI

Posted in Books, Mountains, pictures, Running, Statistics, Travel, University life with tags , , , , , , , , , , , , on April 16, 2018 by xi'an

A recent news editorial in Nature (15 March issue) reminded me of the lectures Louis Aslett gave at the Gregynog Statistical Conference last week, on the advanced use of cryptography tools to analyse sensitive and private data. Lectures that reminded me of a graduate course I took on cryptography and coding, in Paris 6, and which led me to visit a lab at the Université de Limoges during my conscripted year in the French Navy. With no research outcome. Now, the notion of using encrypted data towards statistical analysis is fascinating in that it may allow for efficient inference and personal data protection at the same time. As opposed to earlier solutions of anonymisation that introduced noise and data degradation, not always providing sufficient protection of privacy. Encryption that is also the notion at the basis of the Nature editorial. An issue completely missing from the paper, while stressed by Louis, is that this encryption (like Bitcoin) is costly, in order to deter hacking, and hence energy inefficient. Or limiting the amount of data that can be used in such studies, which would turn the idea into a stillborn notion.

Masterclass in Bayesian Statistics in Marseilles next Fall

Posted in Books, Kids, Mountains, pictures, R, Running, Statistics, Travel, University life with tags , , , , , , , , , , , , , , , , on April 9, 2018 by xi'an

This post is to announce a second occurrence of the exciting “masterclass in Bayesian Statistics” that we organised in 2016, near Marseilles. It will take place on 22-26 October 2018 once more at CIRM (Centre International de Recherches Mathématiques, Luminy, Marseilles, France). The targeted audience includes all scientists interested in learning how Bayesian inference may be used to tackle the practical problems they face in their own research. In particular PhD students and post-docs should benefit most directly from this masterclass. Among the invited speakers, Kerrie Mengersen from QUT, Brisbane, visiting Marseilles this Fall, will deliver a series of lectures on the interface between Bayesian statistics and applied modelling, Havard Rue from KAUST will talk on computing with INLA, and Aki Vehtari from Aalto U, Helsinki, will give a course on Bayesian model assessment and model choice. There will be two tutorials on R and on Stan.

All interested participants in this masterclass should pre-register as early as possible, given that the total attendance is limited to roughly 90 participants. Some specific funding for local expenses (i.e., food + accommodation on-siteat CIRM) is available (thanks to CIRM, and potentially to Fondation Jacques Hadamard, to be confirmed); this funding will be attributed by the scientific committee, with high priority to PhD students and post-docs.
