Robust goodness-of-fit test with kernels -- now out in JMLR! jmlr.org/papers/v26/2... - Existing kernel-based goodness-of-fit tests are not necessarily robust. We explain why in the paper. - We propose a simple yet provably robust extension. Joint work with @fxbriol.bsky.social

The recording of my talk on 'Multilevel neural simulation-based inference' at the 'One World Approximate Bayesian Inference' seminar series is now available on YouTube. Link: www.youtube.com/watch?v=hBWd...

Approximate Bayes Seminar@approxbayesseminar.bsky.social · 9mo ago

The 1st OWABI talk of the Season will be given by François-Xavier Briol (University College London). who will talk about "Multilevel neural simulation-based inference".

I’ll be giving a talk on a recently accepted NeurIPS paper at the next OWABI seminar on Thursday. The talk will cover simulation-based inference and how you can enhance accuracy when you have cheap approximate simulators at hand.
