Abstract

En 中文

• Extended the usage of the trajectory prediction model from the transportation domain. • Predicted particle trajectories in three-dimensional discrete element simulation. • Introduced feature engineering for periodic and Lees–Edwards boundary conditions. • Enhanced accuracy by introducing position and velocity-centric training strategies.
