On the generalization ability of coarse-grained molecular dynamics models for non-equilibrium processes

no code implementations17 Sep 2024 Liyao Lyu, Huan Lei

While a CG model can be constructed by projecting the full dynamics onto a set of resolved variables, the dynamics of the CG variables can recover the full dynamics only when the conditional distribution of the unresolved variables is close to the one associated with the particular projection operator.
