NeurIPS 2026 in Paris, and in Sydney, and in Atlanta

Posted in Statistics with tags , , , , , , , , , , , , , , on May 21, 2026 by xi'an

NeurIPS 2026 is calling for workshops. With deadline 06 June. It made me realize that, this year, NeurIPS will be held across three locations: Sydney as the main location, plus Paris and Atlanta as quasi mirrors. In fact, the European venue was selected by ELLIS to build on the success of EurIPS. Notably, Paris will mark the first time NeurIPS has an official European parallel conference where authors can present their accepted papers without registering for Sydney. NeurIPS workshops in Paris will take place on December 12–13. Another significant argument that mirror meetings are coming to a place near(er and nearer) to you!

Un Diario del Año de les Tapes

On my five-day stay in Sevilla, I got reacquainted with the small streets of the old town, and those of Cadiz for a sunny if short day outing, both that share some similarity with Venice!, as long as the bank of the Guadalquivir where I sent training every early morning. (If missing the opportunity of running the Cádiz media maratón with a last-minute bib a colleague of my wife had procured, due to a lack of favourable public transportation. I was further unsure running even relaxedly a half-marathon a week before my favourite half-marathon was such a great idea.)) I also enjoyed very much the company of the young statisticians and operation researchers at 5SYSORM, including discussions with Antía Enríquez about network scale-up methods, which I had heard off previously (but wondered at the matter of over-counting), alas missing the plenary by Rosa E. Lillo, and with  Adam Olivares about modelling stochastically ordered pairs through a mixture representation (above) I was unaware off. (Also kudos to all participants for sticking to inglés while I was the only participant not fluent in español!)

Foodwise, I (over?!) sampled half-a dozen tapas bars, both in Sevilla and Cádiz, with varying returns, but came back with several great experiences and the (obvious) rule that back-street, low-key, bars, with some pensioner patrons, were to be preferred. Not much greens though, apart from a nearby farmers’ market! (Sorry for the catalán tapes, as I could not find an Andalusian word that sounded like Peste, but with a positive vibe!!!)

Unsurprisingly, I did not have much time to read, except in trains and planes, but finished Les Chaînes de Markov by Noham Selcer, whose title is more a pretence than a driving line. As the story painfully unrolls along the uninteresting couple issues of a (former) maths teacher and a French literature teacher. With artificial dialogues and an overall whining tone that gave me toothaches! There is no redeeming character in the novel, which furthermore describes rural places in Normandie in the worst possible terms. I also tried to complete reading Juice by Tom Winton, but I gave up on this post-apocalyptic story where the climate crisis does not stop radical eco-warriors to flight around the World to assassinate descendants of the powerful people who could have acted against climate change, a poor merge of Mad Max (Oz, of course!) and The Road . Very binary. It took me 50 pages to realise the story was set in the Northwestern part of Australia. And another 50 page to give up! I also started The Witcher Season 4 a few days before leaving, with a new actor William Hemsworth replacing Henry Cavill, “as charismatic as a bollard with a wig”, a season that proves a complete disaster, in part but only in part because the original story itself deteriorates at this point. I stopped early, once I reached a dreadful anime of the vampyre’s background.

Nature tidbits [23 October 2025]

In this October issue of nature, plenty of the “usual” topics, namely AI and Trump.2.0 wrecking balls, along with two cosmology entries that related to my trip to the early universe last week, and a pros-and-cons opposition about animal testing,

a discussion on the nature of the “little red dots” that have been recently observed and whose nature remains open, the most popular explanation (I was given during lunch) being black holes surrounded by gas (even though I cannot understand why the gas is not attracted by the black hole!) [and would have produced a more exciting cover!]

a review of the recent book Discordance: The Troubled History of the Hubble Constant by Jim Baggott, entitled Why we still don’t understand the Universe — even after a century of dispute! A review that regrets that more time is spent on the Hubble “constant” (which varies with time!) rather than more controversial issues like dark matter and dark energy (And strangely bemoans that the book is focussed on scientific developments, missing sociological ones. Duh?! (Bonus for a picture of suit-and-tie Edwin Hubble sitting at the centre of a telescope),

two entries on the well-being [or lack thereof] of PhD students, with nothing particularly surprising (eg, inclusivity and respect help!), and Brazil, Australia and Italy ranking top locations but in a comparative study that does not mention France (as often in international comparisons found in Nature) despite the place being in the top 10 countries delivering PhD degrees, not that I believe PhD students are particularly well-treated in French academia!, the (unexplained) surprise being Italy ranking so high given the close resemblance between the two countries (low stipends, shortage of postdoc and permanent positions, high teaching loads for the advisor, limited travel budgets),

a conference (purposedly) made of AI-written papers reviewed by AI referees, Agents4Science 2025, how universities are rushed into adapting to AI-fluent students, whose skills are changing, and the rise in fake authors produced by paper mills, with a limited range of acceptable solutions,

why Trump 2.0‘s blackmail on pharmaceutical companies is counter-productive and likely to slow down progress, and why his massive increase of highly qualified scientists is shooting (or nuking) USelf in the foot, given the huge proportion) of im/emigrated Nobel prize winners (for physics, chemistry, and medicine), along the (post-) Nobel prize in economics is a direct or indirect reply to this regression by awarding the Prize to economists who worked on the importance of creativity and science on growth (not very surprising at first look!)

get up, clean up, don’t give up the files (and the termites)

As I was trying early July to upgrade my current version of Ubuntu (after a year of procrastination) to 24.04 (Noble Numbat!), I found there was no enough space on the partition element where the upgrade was to take place. I thus started removing superfluous applications, until removing a clock induced a massive removal of attached files and required reinstalling the missing theme to log in…

1924 sudo apt-get autoremove
1926  sudo apt-get autoclean
1929  sudo du -d 1 -h
1932  shutdown -r now
1934  apt-get install sddm-theme-breeze
1935  sudo apt-get install sddm-theme-breeze
1936  sudo apt-get install --reinstall plasma-desktop
1941  logout
1943  sudo apt list --installed | grep -i linux-image
1946  sudo du -h /var/lib/snapd/snaps
1947  sudo journalctl --disk-usage
1957  sudo apt remove linux-image-5.4.0-97-generic
1961  sudo apt remove linux-image-5.4.0-71-generic

I then realised older versions of the Linux kernel were store on that space and eating most of that precious space (as numbats are eating termites) and removed most of these versions with no visible damage. The same issue (of the missing breeze theme preventing regular login) occurred once again at the upgrade stage, with the same patch.
