last call for O’Bayes in Warwick

This is a last call for late participants or would-be participants to the O’Bayes conference at the end of the month, in Warwick on 28 June – 02 July, and right after the BNP 12 conference. Posters can still be submitted to me and registrat…

Lawrence D. Brown PhD Student Award

[Reproduced from the IMS Bulletin, an announcement of a travel award for PhD students in celebration of my friend Larry Brown!] Lawrence D. Brown (1940-2018), Miers Busch Professor and Professor of Statistics at The Wharton School, University of Pennsylvania, had a distinguished academic career with groundbreaking contributions to a range of fields in theoretical and […]

Bayesian Inference, at £1400 per chapter…

Another unsolicited email (“This is a friendly reminder that….”) from a UK operator called IntechOpen about publishing a chapter in an Open Access book about Bayesian Inference. And edited by Tang Niansheng. As detailed on the publisher page “The aim of this book is to introduce the newly developed Bayesian methods, including Bayesian variable selection […]

logicomix redux

I had not made the link until the last speaker of the 50 years of Dauphine commemoration was introduced that he was one of the authors of Logicomix. He spoke of the mathematical modeling of neurons and brain activity, rather than comics, but at a very low level that he called cartoonesque. It is a […]

postdoc position still open

The post-doctoral position supported by the ANR funding of our Paris-Saclay-Montpellier research conglomerate on approximate Bayesian inference and computation remains open for the time being. We are more particularly looking for candidates with a strong background in mathematical statistics, esp. Bayesian non-parametrics, towards the analysis of the limiting behaviour of approximate Bayesian inference. Candidates should […]

ABC in Grenoble, 19-20 March 2020

The next occurrence of the “ABC in…” workshops will take place in Grenoble, France, on 19-20 March 2020. Both local organising and international scientific committees have been constituted and the program should soon be constructed, along with calls to contributions launched at the same time. As in most earlier versions of the workshops (ABC in […]

Garrigue administrative

A central page in Le Monde of this week (May 08), about the conundrum of dealing with the dozens of thousands of handwritten pages left by Alexandre Grothendiek, from trying to make sense of the contents to assessing the monetary value (!) of such documents. Mentioning that the most reasonable solution would be to extend […]

O’Bayes 2019 conference program

The full and definitive program of the O’Bayes 2019 conference in Warwick is now on line. Including discussants for all papers. And the three [and free] tutorials on Friday afternoon, 28 June, on model selection (M. Barbieri), MCMC recent advances (G.O. Roberts) and BART (E.I. George). Registration remains open at the reduced rate and submissions […]

PhD studenships at Warwick

There is an exciting opening for several PhD positions at Warwick, in the departments of Statistics and of Mathematics, as part of the Centre for Doctoral Training in Mathematics and Statistics newly created by the University. CDT studentships are funded for four years and funding is open to students from the European Union without restrictions. […]

over-confident about mis-specified models?

Ziheng Yang and Tianqui Zhu published a paper in PNAS last year that criticises Bayesian posterior probabilities used in the comparison of models under misspecification as “overconfident”. The paper is written from a phylogeneticist point of view, rather than from a statistician’s perspective, as shown by the Editor in charge of the paper [although I […]

visualising bias and unbiasedness

A question on X validated led me to wonder at the point made by Christopher Bishop in his Pattern Recognition and Machine Learning book about the MLE of the Normal variance being biased. As it is illustrated by the above graph that opposes the true and green distribution of the data (made of two points) […]

the Montréal declarAIon

In conjunction with Yoshua Bengio being one of the three recipients of the 2018 Alan Turing award, Nature ran an interview of him about the Montréal Déclaration for a responsible AI, which he launched at NeurIPS last December. “Self-regulation is not going to work. Do you think that voluntary taxation works? It doesn’t.” Reflecting on […]

instituts interdisciplinaires d’intelligence artificielle

Four French institutes have just been selected by [the jury mandated by] the French Government to become interdisciplinary institutes for artificial intelligence (3IA): •    ANITI (Toulouse), centred at l’Université Fédérale Toulouse Midi-Pyrénées •    MIAI @ Grenoble Alpes (Grenoble), centred at l’Université Grenoble Alpes •    PRAIRIE (Paris), centred à Inria •    3IA Côte d’Azur (Nice), centred […]
