Therefore, the objective of this research is the multi-label classification of adverse drug reactions by incorporating transformers-based graph neural networks (GNNs). This paper presents a new model called GTransfNN (graph-based transformer neural network) that leverages graphs with transformers to ...
如果我们要进行邻域聚合的多个并行头,并用注意力机制(即加权和)代替对邻域的求和,我们就会得到图注意力网络(Graph Attention Network, GAT),如上图左所示。从某种程度上说,GAT 与 attention 已经完成了形式上的统一。还有一点需要注意的是,GNN 的图连接通常不是全连接的,而 Transformer 的关于稀疏性的研究也证明了...

在本文中,我们提出了一种新颖的方法,称为GANDALF(Graph-based TrANsformer and Data Augmentation Active Learning Framework),即基于图的Transformer与数据增强主动学习框架,用于在多标签环境下结合样本选择和数据增强。传统的样本选择方法大多集中于单标签环境,在这种环境下,每个样本只有一个疾病标签。然而,当一个样本可能...
TransGNN: Harnessing the Collaborative Power of Transformers and Graph Neural Networks for Recommender Systems 方法:论文提出了TransGNN模型,通过交替使用Transformer和GNN层来相互增强它们的能力。TransGNN利用Transformer层扩大了接受野,并将信息聚合从边缘中解耦,从而增强了GNN的信息传递能力。
Graph Neural Networks (GNNs) have been widely applied to various fields due to their powerful representations of graph-structured data. Despite the success of GNNs, most existing GNNs are designed to learn node representations on the fixed and homogeneous graphs. The limitations especially become prob...
