New geometry-based fragmentation method enhances molecular representation learning

By PulseAugur Editorial · [1 sources] ·

Researchers have developed a novel geometry-based fragmentation method for molecular representations, moving beyond predefined chemical rules. This approach treats fragmentation as a radius-constrained optimization problem, similar to the k-center formulation, allowing for flexible control over fragment size and the creation of multiscale representations. By integrating these multiscale fragments with 3D conformational data and p-SMILES representations into a multimodal machine learning model, the study demonstrates improved polymer property prediction accuracy compared to models relying solely on p-SMILES.

    Towards Multiscale Molecular Representation Learning through Geometry-Based Fragmentation for Polymer Property Prediction

    arXiv:2611.07998v1 Announce Type: new Abstract: It is well established that molecular substructures can contribute unequally to chemical and physical properties, with specific motifs or side chains often playing dominant roles. Fragment-based representations have therefore emerge…
