The 5th Bayesian Young Statisticians Meeting, BAYSM2020, will take place in Kunming, China (June 26-27, 2020) as a satellite to the ISBA 2020 world meeting. BAYSM is the official conference of j-ISBA, the junior section of the International Society for Bayesian Analysis. It is intended for Ph.D. Students, M.S. Students, Post-Docs, Young and Junior researchers working in the field of Bayesian statistics, providing an opportunity to connect with the Bayesian community at large. Senior discussants will be present at each session, providing participants with hints, suggestions and comments to their work. Distinguished professors of the Bayesian community will also participate as keynote speakers, making an altogether exciting program.

Registration is now open ( and will be available with an early bird discount until May 1, 2020. The event will be hosted at the Science Hall of Yunnan University (Kunming, China) right before ISBA 2020 world meeting. BAYSM 2020 will include social events, providing the opportunity to get to know other junior Bayesians.

Young researchers interested in giving a talk or presenting a poster are invited to submit an extended abstract by March 29, 2020. All the instructions for the abstract submission are reported at the page

Thanks to the generous support of ISBA, a number of travel awards are available to support young researchers.

Keynote speakers:

tea tasting at Van Cha

This recent trip to Vancouver gave me the opportunity of enjoying a Chinese tea tasting experience. On my last visit to the city, I had noticed a small tea shop very near the convention centre but could not find the time to stop there. This round I took advantage of the AABI lunch break to get back to the shop, which was open (on a Sunday), and sat for a ripe Pu-Ehr tasting. A fatal if minor mistake in ordering, namely that this was Pu-Ehr withing a dried yuzu shell, which gave the tea a mixed taste of fruit and tea, as least for the first brews. And remaining very far from the very earthy tastes I was expecting. (But it reminded me of a tangerine based Pu-Ehr Yulia gave me last time we went to Banff. And I missed an ice climbing opportunity!)
This was nonetheless a very pleasant tasting experience, with the tea hostess brewing one tiny tea pot after another, including a first one to wet and clean the tea, with very short infusion times, and tea rounds keeping their strong flavour even after several passes. In a very quiet atmosphere altogether, with a well-used piece of wood (as shown on top) in lieu of a sink to get rid of the water used to warm and clean pots and mugs (and a clay frog which role remained mysterious throughout!).
At some point in the degustation, another customer came in, obviously from a quite different league as he was carrying his own tea pancake, from which the hostess extracted a few grams and processed most carefully. This must have been an exceptional tea as she was rewarded by a small cup of the first brew, which she seemed to appreciate a lot (albeit in Chinese so I could not say).
As I was about to leave, having spent more time than expected and drank five brews of my tea, plus extra cups of a delicate Oolong, hence missing a talk by Matt Hoffman to which I was looking forward!, I discussed for a little while with this connoisseur, who told me of the importance of using porous clay pots and not mix them for different teas. Incidentally he was also quite dismissive of Japanese teas, (iron) teapots, and tea ceremony, which I found in petto a rather amusing attitude (if expected from some aficionados).

Nature worries

Posted in Statistics with tags , , , , , , , , , , , , on October 9, 2019 by xi'an

In the 29 August issue, worries about the collapse of the Italian government coalition for research (as the said government had pledge to return funding to 2009 [higher!] levels), Brexit as in every issue (and the mind of every EU researcher working in the UK), facial recognition technology that grows much faster than the legal protections which should come with it, thanks to big tech companies like Amazon and Google. In Western countries, not China… One acute point in the tribune being the lack of open source software to check for biases. More worries about Amazon, the real one!, with Bolsonaro turning his indifference if not active support of the widespread forest fires into a nationalist campaign. And cutting 80,000 science scholarships. Worries on the ethnic biases in genetic studies and the All of Us study‘s attempt to correct that (study run by a genetic company called Color, which purpose is to broaden the access to genetic counseling to under-represented populations). Further worries on fighting self-citations (with John Ioannidis involved in the analysis). With examples reaching a 94% rate for India’s most cited researcher.

Nature snippets

In the August 1 issue of Nature I took with me to Japan, there were many entries of interest. The first pages included a tribune (“personal take on events”) by a professor of oceanography calling for a stop to the construction of the TMT telescope on the Mauna Kea mountain. While I am totally ignorant of the conditions of this construction and in particular of the possible ecological effects on a fragile altitude environment, the tribune is fairly confusing invoking mostly communitarian and religious, rather than scientific ones. And referring to Western science and Protestant missionaries as misrepresenting a principle of caution. While not seeing the contradiction in suggesting the move of the observatory to the Canary Islands, which were (also) invaded by Spanish settlers in the 13th century.

Among other news, Indonesia following regional tendencies to nationalise research by forcing foreign researchers to have their data vetted by the national research agency and to include Indonesian nationals in their projects. And, although this now sounds stale news, the worry about the buffoonesque Prime Minister of the UK. And of the eugenic tendencies of his cunning advisor… A longer article by Patrick Riley from Google on three problems with machine learning, from splitting the data inappropriately (biases in the data collection) to hidden variables (unsuspected confounders) to mistaking the objective (impact of the loss function used to learn the predictive function). (Were these warnings heeded in the following paper claiming that deep learning was better at predicting kidney failures?)  Another paper of personal interest was reporting a successful experiment in Guangzhou, China, infecting tiger mosquitoes with a bacteria to make the wild population sterile. While tiger mosquitoes have reached the Greater Paris area,  and are thus becoming a nuisance, releasing 5 million more mosquitoes per week in the wild may not sound like the desired solution but since the additional mosquitoes are overwhelmingly male, we would not feel the sting of this measure! The issue also contained a review paper on memory editing for clinical treatment of psychopathology, which is part of the 150 years of Nature anniversary collection, but that I did not read (or else I forgot!)
