Learning the Neighborhood: Contrast-Free Multimodal Self-Supervised Molecular Graph Pretraining

arXiv:2509.22468v2 Announce Type: replace Abstract: High-quality molecular representations are essential for property prediction and molecular design, yet large labeled datasets remain scarce. While self-supervised pretraining on molecular graphs has shown promise, many existing approaches either depend on hand-crafted augmentations or complex generative objectives, and often rely solely on 2D topology, leaving valuable 3D structural information underutilized. To address this gap, we introduce C-FREE (Contrast-Free Representation learning on Ego-nets), a simple framework that integrates 2D gra
The increasing availability of computational resources and advancements in machine learning are driving innovations in molecular representation learning, crucial for drug discovery and material science.
Improved molecular representations accelerate the discovery of new drugs and materials, impacting pharmaceutical, biotechnology, and chemical industries significantly.
The ability to more accurately and efficiently predict molecular properties with less reliance on large labeled datasets or complex augmentations changes the landscape of molecular design workflows.
