don’t be late for BayesComp’2020

An important reminder that October 14 is the deadline for regular registration to BayesComp 2020 as late fees will apply afterwards!!! The conference looks attractive enough to agree to pay more, but still…

O’Bayes 2019: poster deadline extension

Posted in pictures, Statistics, Travel, University life with tags , , , , , , , , , on January 31, 2019 by xi'an

For potential participants to the ISBA O’Bayes 2019 conference in Warwick next June 28 – July 02, that is, almost everyone except the participants who have already submitted!, this post is to announce that the deadline for poster submission has just been extended till March 15, to account for BNP 12 potential participants having not yet been notified of the accepted contributed sessions. Or the poster presentations there, since the same poster can be discussed at both places, by all means!  (Thank you Robin for pointing this out!) As an aside, the construction of the webpage is still under development for registration fees (low) and university accommodations (cheap), but should be out next week! (The current links are to BAYSM 2018, which took place last year, obviously.)

ABC and ISBA in Edinburgh [early registration deadline]

Just a reminder that the deadline for early registration at ISBA 2018, and hence at the satellite workshop ABC in Edinburgh, since there is alas no separate access to the later, is drawing near! Given the already rather sharp rates of £380 for ISBA members and £250 at this time, and the incoming rise (to plummet at $1,1000 for registering on site!!), it would be advised to register prior to April 15, if you intend to attend…

(Disclaimer: I am not part of the organising committee of either event. And I have already written several posts here and there complaining on the absurd inflation of conference fees.)


3rd conference on geometric science[s] of information

Posted in Books, pictures, Statistics, Travel, University life with tags , , , , , , , , , , on January 31, 2017 by xi'an

A call for contribution to the 3rd Conference on Geometric Science of Information that I was asked to advertise. (I would have used Sciences instead of Science.) With a nice background picture related to Adelard de Bath, who among other things in natural philosophy introduced the Hindu-Arabic numerals in Europe [and later to America, even though the use of Arabic numerals there may soon come to an end]. And which Latin translation of Euclid’s Elements includes the above picture. The conference is on November 7-9, 2017, in the centre of Paris (Écoles de Mines, next to Luxembourg). (As I cannot spot the registration rates of that conference on the website, I cannot at this stage bring full support to the conference!)

ABC in Stockholm [on-board again]

abcruiseAfter a smooth cruise from Helsinki to Stockholm, a glorious sunrise over the Ålend Islands, and a morning break for getting an hasty view of the city, ABC in Helsinki (a.k.a. ABCruise) resumed while still in Stockholm. The first talk was by Laurent Calvet about dynamic (state-space) models, when the likelihood is not available and replaced with a proximity between the observed and the simulated observables, at each discrete time in the series. The authors are using a proxy predictive for the incoming observable and derive an optimal—in a non-parametric sense—bandwidth based on this proxy. Michael Gutmann then gave a presentation that somewhat connected with his talk at ABC in Roma, and poster at NIPS 2014, about using Bayesian optimisation to reduce the rejections in ABC algorithms. Which means building a model of a discrepancy or distance by Bayesian optimisation. I definitely like this perspective as it reduces the simulation to one of a discrepancy (after a learning step). And does not require a threshold. Aki Vehtari expanded on this idea with a series of illustrations. A difficulty I have with the approach is the construction of the acquisition function… The last session while pretty late was definitely exciting with talks by Richard Wilkinson on surrogate or emulator models, which goes very much in a direction I support, namely that approximate models should be accepted on their own, by Julien Stoehr with clustering and machine learning tools to incorporate more summary statistics, and Tim Meeds who concluded with two (small) talks!, centred on the notion of deterministic algorithms that explicitly incorporate the random generators within the comparison, resulting in post-simulation recentering à la Beaumont et al. (2003), plus new advances with further incorporations of those random generators turned deterministic functions within variational Bayes inference

On Wednesday morning, we will land back in Helsinki and head back to our respective homes, after another exciting ABC in… workshop. I am terribly impressed by the way this workshop at sea operated, providing perfect opportunities for informal interactions and collaborations, without ever getting claustrophobic or dense. Enjoying very long days also helped. While it seems unlikely we can repeat this successful implementation, I hope we can aim at similar formats in the coming occurrences. Kitos paljon to our Finnish hosts!
