Multimodal Molecular Representation Learning with Graph Neural Networks, Deep & Cross Networks, and SMILES Embeddings
arXiv:2607.05736v1 Announce Type: new Abstract: Molecular property prediction often relies on isolated data modalities, where continuous 3D graph neural networks (GNNs) struggle to efficiently capture long-range topological dependencies and exact macroscopic heuristics. In this work, we introduce a parameter-efficient Tri-Branch Modular Fusion Neural Network that synthesizes three orthogonal modalities: 3D spatial geometry (SchNet), discrete topological grammar (SMILES via ChemBERTa), and explicit macroscopic physicochemical descriptors (Deep & Cross Network). By bypassing standard scalar read
The increasing complexity of molecular data and the limitations of isolated modalities are driving the development of more sophisticated, multimodal AI architectures.
This research introduces a novel, parameter-efficient approach to molecular property prediction that improves accuracy and efficiency, critical for drug discovery and materials science.
The ability to synthesize discrete, continuous, and macroscopic molecular data modalities more effectively will accelerate the design and discovery of new molecules.
