AI Narratives: A history of imaginative thinking about intelligent machines is a 2020 collective book edited by Stephen Cave, Kanta Dihal, and Sarah Dillon, with about twenty contributing authors, through a series of 16 chapters on the relation between culture (literature, films) and our societal approach to AI, with varying perspectives, some overlap between chapters, a wide range of extrapolation, especially in relation with the oldest books (like Homer’s) and quotes from both books I enjoyed and books I had not heard of, to add to my to-red pile, like Roderick. Predominant place of Blade Runner, of Ĉapek’s Rossum’s Universal Robots, not only for introducing the term, and of Asimov, but also a detailed analysis of the great, thought-provoking, Ann Leckie’s Ancillary Justice. With a realization that Gibson’s Neuromancer had aged quite a lot… For the modern times, very little outside the US-UK realm, as for instance no mention made of Jules Verne or René Barjavel, although Zola makes an appearance when describing workers as automats, neither of the Germanic literature (from the Grimm Brothers onwards), nor of the non-negligible USSR science fiction production, nor yet of the Chinese input, like The three body problem. Other books that could have made it: the Murderbot diaries, and The Alchemy Wars trilogy, for digging into the blurry border between humans and AIs; A Memory Called Empire, for a clever approach to mind uploading, as well as the masterly Never let me go by Ishiguro, both dealing with a future where copies of humans The Amazing Adventures of Kavalier & Clay for the golem, the short story An Unatural Life, for its highly original take on the legal rights of humanoid robots, A Psalm for the Wild-Built because of… tea and Zen monk, obviously!

Among things I learned from AI Narratives, the story of Alan Turing (figuratively) mansplaining Ada Lovelace on her pronouncement that machines cannot be intelligent since they deliver what they are coded for. The mention of automatos in the Illiad. A mention of 1625 Gabriel Naudé Apologie &tc. that excludes magic as irrational, as well as introducing the term androide. The trivia that the creator of the (fraudulent) automaton chess player, Kempelen, also produced in 1791 an authentic if brainless speaking machine. The realisation that E.M Forster also wrote a futuristic novel, The Machine Stops (as well as the precursor of the symbolists, Villiers de l’Isle Adam, with L’Ève Future). Another trivia that cyberpunk first appeared in a 1983 short story by Bruce Bethke. A discussion of the elaborate Culture constructed by Iain Banks, albeit through volumes in the series I hade not read, along with the concept of OCP for outside context problem, akin to Taleb’s Black Swan. The least interesting (and final) chapter in the book is paradoxically the closest to data analysis, when Recchia runs a rather low-tech assessment of a subtitle dataset in relation with AI, if referring to Tufte’s rule of the baselin in the notes (p405).

Definitely enjoyable book, then, even though I mostly skimmed through the chapters during a day-trip to Lille on a Bank (!) holiday. Reading through it made me muse rather belatedly of a parallel between AI scare or adoration, and the non-AI societies, where individuals are (also) part of a structure large enough to miss the larger picture. From building pyramids to being part of the global economy. (This followed mostly from my surprise in seeing Dickens, Trollope, and Zola included in the discussion.)

a most unexpected citaXion!

In a conversation between (Canadian) Christian Genest (whom I first met in 1986, in a dinner cruise of Lac Léman organised by the French Statistical Society for its national meeting in Lausanne) and David Bellhouse that recently appeared in the International Statistical Review of January 2025 figures the following bit that quotes my… review of Bellhouse’s  William Playfair!

Christian Genest: More recently, you produced some very original work on William Playfair (Bellhouse, 2023), who is generally regarded as the founder of graphical methods in statistics. What about it?

David Bellhouse: The best I can do here is to quote from Christian Robert’s review of my book in Chance (Robert, 2024).

‘The impressions I kept from reading this detailed account of a perfect unknown (as far as I am concerned) are of a rather unpleasant, unappealing, unsuccessful, fame-seeking, inefficient, short-sighted, self-aggrandizing, bigoted, dishonest character, a ‘rascal’ in Stieglerian terms, running away from his debtors for most of his life, with many jail episodes for bankruptcy, while trying to make a living from all sorts of doomed commercial projects, ill-conceived scams, short-lived blackmailing attempts, and mediocre books that did not sell to many’.

I am glad David enjoyed the quote (to which I may have invested more effort than usual to give it a sort of Dickensian flavour). Incidentally, I learned there that David was a French horn player (which would have been my first choice of musical instrument had I been given a choice when starting playing music!)

William (Bill) Strawderman (1941-2024)

Earlier today, I was informed by several of our mutual friends that my long-time friend Bill Strawderman had sadly passed away yesterday, after fighting a cancer for the past months. I remember quite clearly meeting Bill in the Fall of 1988 in front of White Hall, which hosted the Cornell maths department at the time, as he was visiting George Casella from Rutgers where he spent most of his career. I was most eager to meet him as I had worked on several of his landmark papers during my PhD on shrinkage estimation, as well as a bit impressed. But his kindness, modesty, and congenial personality quickly put me at ease and we spent the rest of his visit discussing shrinkage but also literature and music. Especially Dickens! After that we met and collaborated quite regularly, to the point he started visiting France upon my return, at Paris 6 (Pierre & Marie Curie) University first, and then in Rouen, where he became a adjunct professor and launched a life-long collaboration and friendship with Dominique Fourdrinier. As my interest in shrinkage estimation dwindled along the years, we did not keep collaborating for the past two decades, but we remained in touch and I was very happy to participate in his 80th anniversary celebration in Rutgers two years ago. His contributions to the field are notable and several papers of his were part of the Bayesian classics I was giving my graduate class a few years ago. From the fabulous minimaxity paper of 1984, along with George Casella, to admissible estimators dominating the positive-part James-Stein estimator, to sufficient conditions of minimaxity for proper Bayes estimators, to decision theoretic properties of Bayesian credible interval estimators, to loss estimation, not to mention his more applied side… Besides his fabulous sense of humour, which made many evenings with him memorable, I will also cherish the memory of a bon vivant who liked good food and good wines, incl. the Calvados apple brandy I would bring him at each of my visits.

Read (in French) L’Anomalie (2020 Prix Goncourt) with difficulties as the time travel paradox behind the story is extremely shallow and uninteresting, with caricatures of mathematicians and of about any other category in guise of characters. Lazy writing at its worst, floors below a standard Paasilinna. On a whim, decided to read Le Grand Meaulnes (in French) which I had not fully read as a teenager, but was remembering as a “classic” I should have read. Ended up being highly disappointed by the book, except for its literary style and the insights on the daily life of in the French countryside before World War I (during whose first days the author, Alain Fournier, was killed in action). Indeed, the setting is puzzlingly fantastic, with the highlight of a costumed and doomed wedding in a remote castle that Meaulnes stumble upon, but with no clear intention and on such a scale as to be completely implausible for a small rural community, plus other glaring inconsistencies like getting lost in one’s own vicinity and reuniting some characters at the end against all odds and logic. Maybe I should have read it as a teenager! I am still bemused it was ranked in the top 101 French favourite novel list… unless readers share the same phantom memory as I of the book being a “must-read”, rather than of the book itself. As a side story, the edition I read dates from 1967 (number 1000 in Livre de Poche!) and looks its age, presumably one of the few books we had at home, courtesy of a family member with duplicates in her library, just like my version of David Copperfield. printed in 1965.

Cooked more of the seasonal vegetables, had oysters with no consequence (despite the current contamination scare on Atlantic and Channel fields, due to heavy rains saturating the nearby sewage systems), and celebrated our son’s 30th birthday (!) in a nice, friendly, and tiny 8ième restaurant with enough Italian roots they did not blink when I asked for an (off-menu) affogato! Which they made with a miso ice cream, surprisingly well-suited to the espresso. The dishes were all pleasantly surprising, with one of the best sweetbread preparation I have ever eaten. Great meal before a (rather arctic!) stroll to the Musée Guimet.

Watched The Night Agent delivering a moderately convincing conspiracy hunt at the core of the US government with improbable escapes and unlikely hunches and obvious red herrings, but an interesting couple of evil killers. Watchable on a lazy, wet weekend, maybe. Also had a go at Leave the World Behind poor and shallow, adapted from a 2020 bestseller with the same title by Rumaan Alam, heavy going, poor characters, poor actors, unbearable music. Only positive point for being included here, its connection with the (horsemen of the) Apocalypse.

Bill’s 80th!!!

“It was the best of times,
it was the worst of times”
[Dickens’ Tale of Two Cities (which plays a role in my friendship with Bill!)]

My flight to NYC last week was uneventful and rather fast and I worked rather well, even though the seat in front of me was inclined to the max for the entire flight! (Still got glimpses of Aline and of Deepwater Horizon from my neighbours.) Taking a very early flight from Paris was great making a full day once in NYC,  but “forcing” me to take a taxi, which almost ended up in disaster since the Über driver did not show up. At all. And never replied to my message. Fortunately trains were running, I was also running despite the broken rib, and I arrived at the airport some time before access was closed, grateful for the low activity that day. I also had another bit of a worrying moment at the US border control in JFK as I ended up in a back-office of the Border Police after the machine could not catch my fingerprints. And another stop at the luggage control as my lack of luggage sounded suspicious!The conference was delightful in celebrating Bill’s carreer and kindness (tinted with the most gentle irony!). Among stories told at the banquet, I was surprised to learn of Bill’s jazz career side, as I had never heard him play the piano or the clarinet! Even though we had chatted about music and literature on many occasions. Since our meeting in 1989… The (scientific side of the) conference included many talks around shrinkage, from loss estimation to predictive estimation, reminding me of the roaring 70’s and 80’s [James-Stein wise]. And demonstrating the impact of Bill’s wor throughout this era (incl. on my own PhD thesis). I started wondering at the (Bayesian) use of the loss estimate, though, as I set myself facing two point estimators attached with two estimators of their loss: it did not seem a particularly good idea to systematically pick the one with the smallest estimate (and Jim Berger confirmed this feeling on a later discussion). Among the talks on less familiar topics (of mine), I discovered work of Genevera Allen‘s on inferring massive network for neuron connections under sparse information. And of Emma Jingfei Zhang, equally centred on network inference, with applications to brain connectivity.

In a somewhat remote connection with Bill’s work (and our joint and hilarious assessment of Pitman closeness), I presented part of our joint and current work with Adrien Hairault and Judith Rousseau on inferring the number of components in a mixture by Bayes factors when the alternative is an infinite mixture (i.e., a Dirichlet process mixture). Of which Ruobin Gong gave a terrific discussion. (With a connection to her current work on Sense and Sensitivity.)

I was most sorry to miss Larry Wasserman’s and Rob Strawderman’s talk to rush back to the airport, the more because I am sure Larry’s talk would have brought a new light on causality (possibly equating it with tequila and mixtures!). The flight back was uneventfull, the plane rather empty and I slept most of the time. Overall,  it was most wonderful to re-connect with so many friends. Most of whom I had not seen for ages, even before the pandemic. And to meet new friends. (Nothing original in the reported feeling, just telling that the break in conferences and workshops was primarily a hatchet job on social relations and friendships.)
