Uncertainty-biased molecular dynamics for learning uniformly accurate interatomic potentials

no code implementations3 Dec 2023 Viktor Zaverkin, David Holzmüller, Henrik Christiansen, Federico Errica, Francesco Alesiani, Makoto Takamoto, Mathias Niepert, Johannes Kästner

Existing biased and unbiased MD simulations, however, are prone to miss either rare events or extrapolative regions -- areas of the configurational space where unreliable predictions are made.

Self-Tuning Hamiltonian Monte Carlo for Accelerated Sampling

no code implementations24 Sep 2023 Henrik Christiansen, Federico Errica, Francesco Alesiani

In the case of alanine dipeptide, by tuning the only free parameter of our loss definition, we find a good correspondence between it and the autocorrelation times, resulting in a $>100$ fold speed up in optimization of simulation parameters compared to a grid-search.
