Official code for the paper "Neural Atoms: Propagating Long-range Interaction in Molecular Graphs through Efficient Communication Channel" (ICLR 2024).
Graph Neural Networks (GNNs) have been widely adopted for drug discovery with molecular graphs. Nevertheless, current GNNs mainly excel in leveraging short-range interactions (SRI) but struggle to capture long-range interactions (LRI), both of which are crucial for determining molecular properties.
To tackle this issue, we propose a method to abstract the collective information of atomic groups into a few Neural Atoms by implicitly projecting the atoms of a molecular. Specifically, we explicitly exchange the information among neural atoms and project them back to the atoms’ representations as an enhancement.
With this mechanism, neural atoms establish the communication channels among distant nodes, effectively reducing the interaction scope of arbitrary node pairs into a single hop.
