An AI architecture inspired by ChatGPT just solved a curse of dimensionality problem that has haunted chemists for decades.
LLM-inspired graph networks can predict molecular energy surfaces in up to 186 dimensions with extreme accuracy. This task was previously thought to be too computationally heavy for any standard computer to handle. By applying the scaling logic of generative AI to chemistry, researchers can now model complex molecules without the usual massive overhead. This means we can simulate the behavior of new drugs and materials with a level of detail that was recently impossible. It turns the black box of chemistry into a predictable, computable landscape.
A large language model-type architecture for high-dimensional molecular potential energy surfaces
arXiv · 2412.03831
Computing high-dimensional potential energy surfaces for molecular systems and materials is considered to be a great challenge in computational chemistry with potential impact in a range of areas including the fundamental prediction of reaction rates. In this paper, we design and discuss an algorithm that has similarities to large language models in generative AI and natural language processing. Specifically, we represent a molecular system as a graph which contains a set of nodes, edges, faces,
