On behalf of some friends, let me quickly advertise an event taking place in London, January 12-13 2026 (sites.google.com/view/lpd-tnn), with an overall focus on 'Geometric methods in probability'. Registration is free but required, and closes on December 1 (i.e. next Monday) - exciting stuff!

However, this changes if you allow for a dilation factor. In particular, there is always some σ = σ(p, q) such that Z(p) is dominated by σ⋅Z(q). After a bit of book-keeping and changing variables for convenience, one can deduce the attached formula.

Very cool (from Ehm-Gneiting-Jordan-Krüger, JRSSB 2016): for mean estimation, all consistent scoring rules can be obtained as conic combinations of 'extremal' consistent scoring rules, with an explicit structure. Similar results hold for quantiles (and perhaps other tasks as well!).

I appreciate that this is technically a comprehensible sentence (and pretty benign in terms of how complex the concepts are), but the density of jargon did hit me with that vague feeling of "am I having a stroke".

Let me advertise a bit our Online Monte Carlo seminar:
This coming Tuesday, we have Giorgos Vasdekis speaking on some very interesting recent work.
Moreover, we have confirmed our speaker line-up through until December - very exciting!
See sites.google.com/view/monte-c... for further details.

A glimpse behind the curtain. Yet more care is needed when looking at things like variational inference with inducing variable approaches (which also occupy an interesting space vis-à-vis conditioning, randomness, etc.).

very cool workshop last week - www.newton.ac.uk/event/oggw03/ - lots of talks from good speakers on interesting works. keen to watch my way through them when I get a moment!

Another one, drafted for the same workshop, but which didn't quite make it - but which I hope will see some use at a future event!

A drafted logo for a past workshop (we ended up going with something else in the end, but I still find this one cute in its own way).

This is indeed in the works (after combing through some of my folders of notes), but in the interim, I can share a few things which I've put up directly as .pdf files on my website (sites.google.com/view/sp-mont...), rather than as blog posts per se. Notes 3-5 are 'new'.
