Minimum Distance Summaries for Robust Neural Posterior Estimation Simulation-based inference (SBI) enables amortized Bayesian inference by first training a neural posterior estimator (NPE) on prior-simulator pairs, typically through low-dimensional summary statistic...

New preprint πŸ“’ arxiv.org/abs/2602.09161 Lead by Sherman Khoo (PhD student at Compass CDT), with Song Liu and Mark Beaumont. We adjust SBI summaries at test time to improve robustness.

In some ways it's too good - turning on the glm module by default broke some of my examples of bad mixing

On further investigation, I could have switched my teaching to this package 10 years ago. Better later than never I guess!

A Wrapper Around rjags to Streamline JAGS Analyses A set of wrappers around rjags functions to run Bayesian analyses in JAGS (specifically, via libjags). A single function call can control adaptive, burn-in, and sampling MCMC phases, with MCMC chains ...

Updating my lecture notes to use jagsUI (kenkellner.com/jagsUI/) in place of rjags, and it's a great fix for lots of minor teaching pain points #rstats
