MR-GNN:预测结构化实体交互的多分辨率双图神经网络

MR-GNN: Multi-Resolution and Dual Graph Neural Network for Predicting Structured Entity Interactions

Nuo Xu, Pinghui Wang, Long Chen, Jing Tao, Junzhou Zhao

摘要:

预测结构化实体之间的相互作用是许多任务的核心,例如药物方案和新材料设计。近年来,图神经网络已成为引人注目的。它们将结构化实体表示为图,然后使用图卷积操作从每个单独的图中提取特征。然而,这些方法具有一些局限性:i)它们的网络仅从固定大小的子图结构中提取特征(即,固定大小的感受野),并且忽略不同大小的子结构中的特征,以及ii)通过独立地考虑每个实体来提取特征,这可能不能有效地反映两个实体之间的交互。为了解决这些问题,我们提出了MR-GNN,一个端到端的图神经网络,具有以下特点:i)它使用基于多分辨率的架构,从每个节点的不同邻域中提取节点特征,ii)它使用双图状态长短期记忆网络(L-STM)来总结每个图的局部特征,并提取成对图之间的交互特征。在真实世界数据集上进行的实验表明,MR-GNN改进了最先进方法的预测。

英文摘要:

Predicting interactions between structured entities lies at the core of numerous tasks such as drug regimen and new material design. In recent years, graph neural networks have become attractive. They represent structured entities as graphs and then extract features from each individual graph using graph convolution operations. However, these methods have some limitations: i) their networks only extract features from a fix-sized subgraph structure (i.e., a fix-sized receptive field) of each node, and ignore features in substructures of different sizes, and ii) features are extracted by considering each entity independently, which may not effectively reflect the interaction between two entities. To resolve these problems, we present MR-GNN, an end-to-end graph neural network with the following features: i) it uses a multi-resolution based architecture to extract node features from different neighborhoods of each node, and, ii) it uses dual graph-state long short-term memory networks (L-STMs) to summarize local features of each graph and extracts the interaction features between pairwise graphs. Experiments conducted on real-world datasets show that MR-GNN improves the prediction of state-of-the-art methods.
