捕捉节点标签的结构相似度is shown to be helpful for泛化,特别是当subtrees的co-occurrence在不同的图之间是稀疏的时候或者是存在噪声边和节点特征的时候。 4.1 graph isomorphism network(GIN) 获得了maximally powerful GNN的条件,之后我们设计了GIN,可能满足定理3中的条件。这个模型泛化了WL test于是可以在GNNs之中...
Graph isomorphism networkMultimodalPredicting protein-ligand binding affinity is essential for understanding protein-ligand interactions and advancing drug discovery. Recent research has demonstrated the advantages of sequence-based models and graph-based models. In this study, we present a novel hybrid ...

1.2.6 Graph Isomorphism Networks (GIN) GIN是基于Weisfeiler-Lehman Isomorphism Test(WL-同构检测)提出的,用于提高GNNs的表达能力的结构。有关WL-test的介绍请见本文附录部分。GIN更新节点的公式为: 其中\epsilon 是一个可学习的常量。 1.3 Task-based Layer GNNs可以用来实现多种类别的任务,针对不同的任务我们需...
4. Graph Isomorphism Network (GIN) 4.1 Theoretical basis GIN 的设计目的:希望将同构的图映射到相同的表示,而将非同构的图映射到不同的表示。 作者发现如果 aggregation mechanism 和 graph-level readout 函数是内射的,那么所得到的 GNN 与 WL test 一样强大,并给出如下定理: ...

In this work, the default graph encoder is the graph isomorphism network (GIN) [49], due to its exceptional ability in graph modeling. Formally, GIN is considered the most powerful GNN model theoretically, as it ensures the injectivity of the passing function. It can be represented as $$\...
