The abstract submission deadline for the ELLIS Workshop on Amortized Probabilistic ML has been extended to October 25th!

You still have time to submit a short abstract on your work in: Amortized Inference, Neural processes, Prior-fitted networks, Sequential Decision-Making, and Foundation models.

Just finished delivering a course on 'Robust and scalable simulation-based inference (SBI)' at Greek Stochastics. This covered an introduction to SBI, open challenges, and some recent contributions from my own group.

New ICML 2025 paper: Robust Spatio-Temporal GP Regression!

We propose a new GP method with linear-in-time cost that is provably robust to outliers. Unlike competitors, our method is fully conjugate and requires no expensive variational inference!

"Cost-aware simulation-based inference" is accepted at AISTATS 2025.

Check out our poster #205 on Sunday May 4th in Hall A-E if you are in Phuket. Finland's rising star @huangdaolang.bsky.social will be there to assist you :D

Cost-aware simulation-based inference
Simulation-based inference (SBI) is the preferred framework for estimating parameters of intractable models in science and engineering. A significant challenge in this context is the large computation...

there's a lot of insight and interesting discussion in the review paper "Simulation-based Bayesian inference under model

My research aims to build a “pressure cooker” for Simulation-Based Inference—maintaining the same computational cost while producing superior results. And yet, in my kitchen, I patiently slow-cook oxtail for three hours in a conventional pot.

Optimizing decision utility in Bayesian experimental design is key to improving downstream decision-making.

Excited to share our #NeurIPS2024 paper on Amortized Decision-Aware Bayesian Experimental Design: arxiv.org/abs/2411.02064

Any single analysis hides an iceberg of uncertainty.

Sensitivity-aware amortized inference explores the iceberg:
⋅ Test alternative priors, likelihoods, and data perturbations
⋅ Deep ensembles flag misspecification issues
⋅ No model refits required during inference

To celebrate the new beginnings on Bluesky, let's reminisce about one of our highlights from the old days:

The unexpected shout-out by @fchollet.bsky.social that made everyone go crazy on the BayesFlow Slack server and led to a 15% increase in GitHub stars.

exciting new seminar series on "Post-Bayes" organised by Jeremias Knoblauch (he is not in Bluesky yet)
📢 Post-Bayesian online seminar series coming!📢
To stay posted, sign up at

We'll discuss cutting-edge methods for posteriors that no longer rely on Bayes Theorem.
(e.g., PAC-Bayes, generalised Bayes, Martingale posteriors, ...)
Pls circulate widely!
