I was complaining about the same thing so my friends got me a katana!
As a large language model developed by OpenAI, I don't have genitals. Would you like to hear me apologising instead?
Oh? This looks pretty aligned to my interests!
Most joint distributions can't cleanly be expressed as the divergence of a vector field (especially in dimensions > 2) so this doesn't apply. Also, you usually don't care about the probability of an event, but rather about an expected outcome under this event. Makes it even less relevant.
Thankfully that's not the current approach! People (shout-out to them!) are working on automatic diffentiation of pre-existing low-level numerical code.

Typically targets an intermediate representation that's universally used (incl Fortran)

A coupling-based approach to f-divergences diagnostics for Markov chain Monte Carlo (Corenflos, Dau) A long-standing gap exists between the theoretical analysis of Markov chain Monte Carlo convergence, which is often based on statistical divergences, and the diagnostics used in practice.

The first talk of the season will be this coming Tuesday (23 September), given by Alexandre Bouchard-Côté from UBC. Alex is a great speaker, so do join if you have the chance!

See sites.google.com/view/monte-c... for details, links, and so on.
It's clearly a technological feat, no question there, but robotaxi is also a misplaced (and somewhat detrimental) effort. A dense integrated public transport simply seems overall better for the majority (some of it may very well be self-driving buses/minibuses!)

New paper on arXiv! And I think it's a good'un 😄

Meet the new Lattice Random Walk (LRW) discretisation for SDEs. It’s radically different from traditional methods like Euler-Maruyama (EM) in that each iteration can only move in discrete steps {-δₓ, 0, δₓ}.
Hold on, I was convinced yours was pronounced Sam Pouvoir???
I do this too. I call it the email sandwich. Sometimes I only answer in the morning, and then I call it the email tartine.
This gives Greek Stochastics vibes.

Please keep your compliments where I can see them.
Someone had way too much fun writing this ☺️

Applications are still open for another two weeks.
If anyone is, or knows anyone who is, looking for a postdoc position to work on the foundations of scalable inference and such... applications for a postdoctoral position at Warwick as a part of the OCEAN project (oceanerc.com) are open until 20th August at warwick-careers.tal.net/vx/appcentre....
OCEAN
OCEAN is an ERC Synergy grant gathering researchers to lay the fundations of the next-generation machine learning algorithms, involving decentralized inference and predictive tasks in the presence …

The physics talks had a lot of this + misspecification

Prepping my post-BayesComp "stock market update" (to be taken with a pinch of salt!) on how different topics fared relative to my expectations / past years.
It was great hanging out! Let's do it in the UK too :D
