Enhanced sampling techniques aim to observe rare events like state transitions in molecular dynamics simulations by using collective variables (CVs).
A new framework called TLC has been proposed to learn CVs directly from time-lagged conditions of a generative model, capturing slow dynamic behavior instead of just static information.
TLC was validated on the Alanine Dipeptide system for two CV-based enhanced sampling tasks, demonstrating superior performance compared to existing machine learning CV discovery methods.
The study introduces a novel approach to learning CVs that could improve accuracy in observing rare events in molecular dynamics simulations.
