MGR recovers kinetic properties from umbrella-sampling with high fidelity
It also enables efficient Bayesian parameter inference for SDEs with sparse observations

Marginal Girsanov Reweighting: Stable Variance Reduction via Neural Ratio Estimation

Recovering unbiased properties from biased or perturbed simulations is a central challenge in rare-event sampling. Classical Girsanov Reweighting (GR) offers a principled solution by yielding exact pa...

Standard Girsanov reweighting gives exact pathwise probability ratios, but its variance often explodes over long horizons, making it impractical for many applications. MGR deals with this problem through classifier-based density ratio estimation.

New pre-print from the lab -- Marginal Girsanov Reweighting: Stable Variance Reduction via Neural Ratio Estimation. We introduce Marginal Girsanov Reweighting (MGR), a way to get more stable Girsanov weights for long time horizons and large systems.

Thrilled to announce that the first paper from Flemming's PhD was accepted as Poster for NeurIPS2025! In this paper we adapt the HollowNet idea from Chen and Duvenaud to equivariant MP networks, to get cheap sample likelihoods for flow-based Boltzmann Generators. Preprint/code coming soon.
