Through iterative convolution operations and feature aggregation, each node can obtain more comprehensive information, improving the learning ability of graph data. Take the target-centered PDI as an example, the initial features p of the targets and the fusion features df of the processed drugs ...
Then, we design a semi-supervised mammogram multigraph convolution neural network downstream model (MMGCN) to perform multi-classifications of mammogram segments encoded in the multigraph nodes. Our proposed frameworks, SSL-MGCN and MMGCN, reduce the need for annotated data to 40% and 60%, ...
基于图神经网络的消息传递思想,我们设计了一个多模态图卷积网络(Multi-modal Graph Convolution Network,MMGCN)框架,该框架可以生成用户和微视频特定模态的表征,以更好地捕捉用户的偏好。具体地说,我们在每个模态上构造一个用户-项目二分图(bipartite graph),并用其邻接节点的拓扑结构和特征来丰富每个节点的表征。通过...

Multi-View Attribute Graph Convolution Networks for Clustering(MAGCN)论文学习笔记 1.论文背景 图神经网络(GNNs)在处理图结构数据方面取得了相当大的成就。然而: (1)现有的方法不能将可学习的权值分配给邻域内的不同节点, (2)并且由于同时忽略了节点属性和图重构,缺乏鲁棒性。
