Still woke up early too early, which let me go for a long run in Mont Royal (which felt almost immediately familiar from earlier runs at MCM 2017!) at dawn and at a pleasant temperature (but missed the top bagel bakery on the way back!). Skipped the morning plenary lectures to complete recommendation letters and finishing a paper submission. But had a terrific lunch with a good friend I had not seen in Covid-times, at a local branch of Kinton Ramen which I already enjoyed in Vancouver as my Airbnb was located on top of it.

I chaired the afternoon Bayesian computations session with Onur Teymur presenting the general spirit of his Neurips 21 paper on black box probabilistic numerics. Mentioning that a new textbook on the topic by Phillip Henning, Michael Osborne, and Hans Kersting had appeared today! The second talk was by Laura Bondi who discussed an ABC model choice approach to assess breast cancer screening. With enough missing data (out of 78051 women followed over 12 years) to lead to an intractable likelihood. Starting with vanilla ABC using 32 summaries and moving to our random forest approach. Unsurprisingly concluding with different top models, but not characterising the identifiability provided by the choice of the summaries. The third talk was by Ryan Chan (fresh Warwick PhD recipient), about a Fusion divide-and-conquer approach that avoids the approximation of earlier approaches. In particular he uses a clever accept-reject algorithm to generate a product of densities using the component densities. A nice trick that Murray explained to me while visiting in Paris lg ast month. (The approach appears to be parameterisation dependent.) The final talk was by Umberto Picchini and in a sort the synthetic likelihood mirror of Massi’s talk yesterday, in the sense of constructing a guided proposal relying on observed summaries. If not comparing both approaches on a given toy like the g-and-k distribution.

Upon my arrival at JFK, Queens, Andrew took me to have unbelievable tortillas in this Guatemaltec restaurant, soft and yummy, almost like pancakes! Along with great food altogether. We also had a pleasant stroll walking through Queens’ lively Jamaica district. Including coming upon a just extinguished fire in a row of shops! On the opposite, I did not see much of New Brunswick, apart from walking by the Harvest Moon brewery where I got a beer (and a tee-shirt) on my earlier visit there.

Read Truthwitch, another disappointment in the series (of recent books), as the universe building could have been great (despite being heavily inspired from Western Europe geography and culture, and in particular of Venezia. Again, I presume I was missing the YA label when I first picked this book! Scenario is rather terrible, full of last second rescues, new and convenient forms of magical powers, while interactions about characters are artificial and predictable, definitely not recommended. (And there are five books in the series!)

Watched The Silent Sea a short Korean TV serie taking place mostly in a Korean infected base on the Moon. While trying to solve the water crisis on a drying Earth (looking red from the Moon). The ending is quite disappointing while the original idea was most appealing. The science (fiction) behind the story is however terrible. (E.g., never use guns in space! And why would astronauts rely on cheap, handheld, lamplights to explore dark tunnels?! And how can you hide stealthy visits to a Moon basis from Earth?! &tc.)

Insane craving for food

Within a couple of weeks, I read two related US stories about ordering food from an insanely far destination, like hand-made frozen pizza from Napoli, Italia, or like one startup called Goldbelly ships frozen food made by some restaurants nationwide. (With a motto of Whatever [food] they dream of, wherever they are.) While I am not consistent in consuming non-local food and drinks, like my mass orderings of Italian wines and Darjeeling teas, and while I’d love to get a new taste of Toukoul’s Ethiopian dishes, a creamy sepia risotto from Da Franz, an okonomiyaki from any street stall in Osaka, and many many other dishes from all over the World, it sounds to me rather debatable to have a special single meal prepared on the other side of the World and delivered immediately to one’s table… Furthermore, one of the perks of dining at fine restaurants is exactly to dine at fine restaurants, not in one’s own room, and having starred chefs’ dishes ending up in reheated frozen plastic containers is certainly killing a major share of the experience.
