摘要:

准确预测分子性质在药物发现及相关领域至关重要。然而,现有图神经网络(GNNs)往往难以同时捕捉分子的局部和全局结构。本研究提出一种多级融合图神经网络(MLFGNN),整合图注意力网络与新型图Transformer,联合建模局部和全局依赖关系。此外,我们引入分子指纹作为互补模态,并提出注意力交互机制以自适应融合不同表示的信息。在多个基准数据集上的大量实验表明,MLFGNN在分类和回归任务中均持续优于现有最优方法。可解释性分析进一步揭示,该模型能有效捕捉任务相关的化学模式,证明了多级和多模态融合在分子表示学习中的实用性。

英文摘要:

Accurate prediction of molecular properties is essential in drug discovery and related fields. However, existing graph neural networks (GNNs) often struggle to simultaneously capture both local and global molecular structures. In this work, we propose a Multi-Level Fusion Graph Neural Network (MLFGNN) that integrates Graph Attention Networks and a novel Graph Transformer to jointly model local and global dependencies. In addition, we incorporate molecular fingerprints as a complementary modality and introduce a mechanism of interaction between attention to adaptively fuse information across representations. Extensive experiments on multiple benchmark datasets demonstrate that MLFGNN consistently outperforms state-of-the-art methods in both classification and regression tasks. Interpretability analysis further reveals that the model effectively captures task-relevant chemical patterns, supporting the usefulness of multi-level and multi-modal fusion in molecular representation learning.
