GNNMF built a multi-view heterogeneous graph by using ATAC-seq sequences, and utilized background coexisting probability and the iterloss to find different lengths of ATAC-seq motifs and optimize the parameter
核心 通过对原图使用扩散技术并且采样得到两个视图,然后通过 GNN 编码和一个投影头得到节点的表示,对于图表示,通过 GNN 编码后首先进行一个池化 Pool 后在接上投影头输出得到图表示。 框架 在这个框架中首先对原始图数据进行数据加强(diffuse: 扩散技术)得到增广图并且采样生成两个两个图,利用两个 GNNgθ(...
GNN在single-view上有很好的泛化性能(往往进行监督的节点分类任务),但是将GNN运用于无监督的属性multi-view图聚类的方法还相对较少。 解决问题 如何在无监督的背景下有效融合multi-view的信息? 如何将GNN学习到的节点嵌入运用于聚类任务?节点嵌入和聚类是两种不同的任务,也就是说节点嵌入用于重构图的结构,所以可能不...

提出的MVPool操作是一种通用的策略,能够被整合在各种的GNN架构中,例如GCN,GAT和GraphSAGE等。通过与GNNs组合,可以在节点分类,图分类以及聚类任务上进行层序表征的学习。在13个广泛使用的基准测试中表明提出方法的有效性。原文链接,代码以及作者主页如下: Hierarchical Multi-View Graph Pooling with Structure Learning...
{P_m}\). Each metapath view is associated with a node feature matrix\({\textbf {X}}_{\varvec{m}}\)and an adjacent matrix\({\textbf {A}}_{\varvec{m}}\). We leverage parameter-sharing GNN encoders\(f\left( \cdot \right)\)to learn node representation\(\left\{ \textbf{H}_...
To address these issues, Anomaly Detection in Online Credit Card data using Optimized Multi-view Heterogeneous Graph Neural Networks (AD-OCCD-MHGNN) is proposed. The method begins by applying Fair Synthetic Minority Oversampling Technique (FSMOTE) to balance the dataset. The Multi-observation ...
Specifically, on the PPI dataset, MUSE outperformed all existing models including single-scale (DrugVQA7and TAG-PPI27), and multi-view methods (GNN-PPI24and HIGH-PPI16). TAG-PPI and DrugVQA, which solely focus on the atomic structure scale, achieved the poorest performance as they neglected ...
