Right, I was looking for the high-res image. Maybe I'll contact him!

Now I'd like to order that stuff on the wall too... How did you go about it? :-)

We are hiring!

We are inviting applications for the Chapman Fellowship in Statistics at Imperial College London.

This is a kind of super-postdoc: 3 years contract, excellent working conditions, and candidates are expected to propose an independent research plan.

Here's how the gradient flow for minimizing KL(pi, target) looks under the Fisher-Rao metric. I thought some probability mass would be disappearing on the left and appearing on the right (i.e. teleportation), like a geodesic under the same metric, but I was very wrong... What's the right intuition?

Hi, many thanks for interest. It is a bit late to arrange for online registration - but I will investigate if we can record the talks. I'll keep you posted about this if we could do it - so it could be made online later.

$Φ$-DVAE: Physics-Informed Dynamical Variational Autoencoders for Unstructured Data Assimilation Incorporating unstructured data into physical models is a challenging problem that is emerging in data assimilation. Traditional approaches focus on well-defined observation operators whose functional...

This afternoon I was privileged to examine Alex Glyn-Davies, who produced a great thesis on aspects of physics-informed inference for DE models (arxiv.org/abs/2209.15609, arxiv.org/abs/2409.07101 and arxiv.org/abs/2409.06560) and some anomaly detection for good measure doi.org/10.1016/j.pa....

If anyone is thinking of registering for this, I understand that there are still some spaces available, but the room this event is taking place in has a limited capacity which is likely to be reached... so to avoid disappointment it would be safer to register sooner rather than later ;-).

Luca (Martino) once told me (when I said "MCMC does not have weights") that this is incorrect (in his Sicilian style): When you reject in MCMC, you increase the weight of the current sample. Chains do have replicates, can be written like a weighted sample. High rejection rate *is* weight degeneracy.

this warms my heart as a telecom engineer :)

Very happy to announce the 2nd RSS/Turing Workshop on Gradient Flows for Sampling, Inference, and Learning to take place on 24th of March, 2025!

Registration is open now: tinyurl.com/rss-turing-g...

Please see the webpage for topics and speakers. Hope to see you all there!

Correct at the moment we have not set up an online registration option...

Indeed, this is a great question. In the averaging setting, this seems to help at various stages of the proof - but I think, in the settings I think of (where slow and fast system has the same drift), one should be able to get away with usual conditions to prove similar stuff...

Splendid stuff; very digestible and usable:

Great stuff indeed
