In the interim, I wanted to advertise our YouTube channel - youtube.com/@montecarlos... - which contains recordings for the bulk of our talks so far (sites.google.com/view/monte-c..., sites.google.com/view/monte-c...). I encourage you to catch up and enjoy them over the intervening months!

Starting from last October, we (@OnlineMCSeminar on Twitter, sites.google.com/view/monte-c...) have been running an online seminar on all aspects of Monte Carlo methods, with about ~30 talks so far. We are currently paused for the summer, expecting to return in September 2025.

Yeah, my guess is that generating pretty images does not necessarily require accurate sampling from the original distribution. That said, increasing the number of discretization steps still improves metrics like FID for DDIM.

If you think the process as targeting at p(x) using proposal q(x, xโ€™) = \int_y p(y|x) p(xโ€™|y) dy, then it should have acceptance 1?

A touch of self-advertisement: I'll be giving a research talk next Tuesday at the Online Monte Carlo Seminar (sites.google.com/view/monte-c...) on one of my favourite topics: the convergence properties of the Random Walk Metropolis algorithm. Please join us!

Post-Bayes seminar series โ€“ seminar

Jeremias Knoblauch and other colleagues and friends in UCL launched a "Post-Bayes seminar series". Their will be many blocks of talks, including a series on PAC-Bayes (probably starting in September 2025).

The first talk (by Jeremias) is next week. Please have a look:

The recording, for anybody who's interested: youtu.be/FRoia-lszVM?.... Well worth a watch!

Can we directly use Ascolani-Lavenant-Zanella on this? I thought their entropy contraction implies spectral gap, spectral gap implies mixing time under warm start.
