Researchers have introduced BiScale-GTR, a novel self-supervised framework for molecular representation learning. This approach utilizes context-grounded shared fragment tokens, where a graph Byte Pair Encoding (graph-BPE) vocabulary is created using Weisfeiler-Lehman (WL)-based fragment identity and recursive decomposition. The framework then grounds each shared fragment token with atom-level GNN representations, allowing for context-dependent representations of the same fragment. A structure-aware fragment Transformer processes these tokens to capture reusable substructure identity, local chemical context, and long-range molecular dependencies, demonstrating strong performance on various molecular machine learning benchmarks.
