arXiv:2606.03232v1 Announce Type: new Abstract: Graph Neural Networks (GNNs) have revolutionized Neural Force Fields for atomistic simulations, achieving near-quantum accuracy at reduced cost, yet adapting these models to new chemical systems requires expensive retraining of foundation models. Inspired by model merging in vision and language processing, we introduce GFFMERGE, the first principled framework for closed-form model merging in GNNs. We exploit the linear structure of message-passing layers and formulate merging as a convex embedding-alignment problem with an analytical solution. Th
The rapid development and widespread adoption of GNNs in scientific computing necessitates more efficient methods for model adaptation and deployment, making merging research timely.
This breakthrough offers a method to significantly reduce the computational cost and time associated with adapting advanced AI models for new scientific applications, accelerating research and development.
The ability to merge GNNs for atomistic simulations efficiently means that instead of expensive retraining, existing foundation models can be fine-tuned via merging, democratizing access to high-accuracy simulations.
