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.

Two months after my PhD defense on RL in POMDP, I finally uploaded the final version of my thesis :)
You can find it here: hdl.handle.net/2268/328700 (manuscript and slides).
Many thanks to my advisors and to the jury members.

📝 Our paper "A Theoretical Justification for Asymmetric Actor-Critic Algorithms" was accepted at #ICML!
Never heard of "asymmetric actor-critic" algorithms? Yet, many successful #RL applications use them (see image).
But these algorithms are not fully understood. Below, we provide some insights.

Addressing Misspecification in Simulation-based Inference through Data-driven Calibration
Driven by steady progress in deep generative modeling, simulation-based inference (SBI) has emerged as the workhorse for inferring the parameters of stochastic simulators. However, recent work has dem...

Reading the recent literature on "neural samplers" is an odd experience. There's a lot of attention drifting towards it (conceivably prompted by the increased attention on diffusion models and the like), and so many people are trying many things. It's a different way of thinking about things to me.
