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.

Congratulations to Rocco Caprio -- thesis defended, minor corrections done and graduation imminent. Thanks to Gareth Roberts and Andrew Duncan for examining the thesis. Rocco is now a Prob-AI-funded research fellow warwick.ac.uk/fac/sci/stat... and I look forward to seeing what comes next.

There are a couple of vacancies in Wollongong for Maths/Stats lecturers:

An announcement, which might be of some interest:

In the period 2022-2024, myself and a number of other postdocs on the "CoSInES" and "Bayes4Health" EPSRC grants were involved in organising a number of internal tutorial workshops, on topics relevant to researchers in computational statistics.

Rocco explains this work, among other things, about 90 minutes in to the [https://www.youtube.com/watch?v=QrPy49eAe9o](recording of the recent RSS Workshop of Gradient Flows).

As evidence that this prediction wasn't too bad, [https://academic.oup.com/biomet/advance-article/doi/10.1093/biomet/asaf061/8223075](Rocco's second paper), showing the fast convergence of the venerable EM algorithm using a rather fun functional analysis argument, is in press for Biometrika.

Applications are still open for another two weeks.

I'm sure this will be the first of many.

Towards Adaptive Self-Normalized Importance Samplers The self-normalized importance sampling (SNIS) estimator is a Monte Carlo estimator widely used to approximate expectations in statistical signal processing and machine learning. The efficiency of S...

🚨 New paper: “Towards Adaptive Self-Normalized IS”, @ IEEE Statistical Signal Processing Workshop.

TLDR;
To estimate µ = E_p[f(θ)] with SNIS, instead of doing MCMC on p(θ) or learning a parametric q(θ), we try MCMC directly on p(θ)| f(θ)-µ | (variance-minimizing proposal).

Somewhere in between several other models: the candidate gives a presentation for around an hour to a larger audience, then there's a closed defence with a panel of examiners for around an hour. (As ever, doing things by zoom probably wasn't optimal, but it worked okay.)
