GFFMERGE: Efficient Merging of Graph Neural Force Fields and Beyond
Researchers have developed GFFMERGE, a novel framework for efficiently merging Graph Neural Network (GNN) models used in atomistic simulations. This method addresses the costly retraining required when adapting GNN force fields to new chemical systems. GFFMERGE leverages the linear structure of GNN layers to formulate merging as a convex problem with an analytical solution, outperforming existing methods and enabling faster, data-efficient convergence.
