The Conference on Neural Information Processing Systems (abbreviated as NeurIPS) will see a mirror version in Paris this Fall, albeit in advance of the main meeting (which starts the week after on 29 November and in New Orleans, hence with a France connection!). The concept is original in that (interested) authors of accepted 2022 NeurIPS papers will present their paper on 23-24 November. Registration is free. But attendance is not guaranteed if the number of registrations exceed the site capacity, in which case attendees will be selected at random.

The participation is free. Registration is, however, compulsory and now open.
Jean-Paul Benzécri (1932-2019)
Posted in Books, pictures, Statistics, University life with tags analyse des correspondances, analyse des données, French statistics, ISUP, Jean-Paul Benzécri, Jussieu, obituary, Paris 6, SAS, Université de Paris, Université Pierre et Marie Curie on December 3, 2019 by xi'anI learned last weekend that Jean-Paul Benzécri had died earlier in the week. He was a leading and charismatic figure of the French renewal in data analysis (or analyse des données) that used mostly algebraic tools to analyse large datasets, while staying as far as possible from the strong abstraction of French statistics at that time. While I did not know him on a personal basis, I remember from my lecturer years there that he used to come to Institut de Statistique de l’Université de Paris (ISUP), Université Pierre et Marie Curie, once a week and meet with a large group of younger statisticians, students and junior faculty, and then talk to them for long hours while walking back and forth along the corridor in Jussieu. Showing extreme dedication from the group as this windowless corridor was particularly ghastly! (I also remember less fondly hours spent over piles and piles of SAS printout trying to make sense of multiple graphs of projections produced by these algebraic methods and feeling there were too many degrees of freedom for them to feel rigorous enough.)
Christian Robert is giving a talk in Jussieu tomorrow
Posted in Statistics, University life with tags Archimedean copulas, composite likelihood, copulas, CREST, Jussieu, Paris, seminar, Université Pierre et Marie Curie on September 26, 2019 by xi'anMy namesake Christian (Yann) Robert (CREST) is giving a seminar tomorrow in Jussieu (Université Pierre & Marie Curie, couloir 16-26, salle 209), between 2 and 3, on composite likelihood estimation method for hierarchical Archimedean copulas defined with multivariate compound distributions. Here is the abstract:
We consider the family of hierarchical Archimedean copulas obtained from multivariate exponential mixture distributions through compounding, as introduced by Cossette et al. (2017). We investigate ways of determining the structure of these copulas and estimating their parameters. An agglomerative clustering technique based on the matrix of Spearman’s rhos, combined with a bootstrap procedure, is used to identify the tree structure. Parameters are estimated through a top-down composite likelihood. The validity of the approach is illustrated through two simulation studies in which the procedure is explained step by step. The composite likelihood method is also compared to the full likelihood method in a simple case where the latter is computable.

-
Rémi Bardenet – CNRS Lille / CRISTAL [10:00]
-
Nicolas Chopin – ENSAE / CREST [11:00]
-
Aymeric Dieuleveut – ENS / DI & INRIA [14:00]

Details and abstracts of the talks are available on the workshop webpage. Attendance is free, but registration is requested towards planning the morning and afternoon coffee breaks. Looking forward seeing ‘Og’s readers there, at least those in the vicinity!
And while I am targetting Parisians, crypto-Bayesians, and nearly-Parisians, there is another day workshop on Bayesian and PAC-Bayesian methods on November 16, at Université Pierre et Marie Curie (campus Jussieu), with invited speakers
and a similar request for (free) registration.
