WebAs a popularly used technique for feature learning in graphs, network embedding aims to represent each node as a low-dimensional vector to support efficient graph analytic tasks, such as node classification, link prediction, and visualization. The key to this representation method is that the embedding vector of a node should preserve its properties in the … WebHierarchical Graph Representation Learning with Differentiable Pooling. Motivation. 众所周知的是，传统的图卷积神经网络，层级间网络特征处理一般是通过直接拼接（concat）或者简单的线性层进行，这种做法忽略了图网络中的层级关系。. 这边我们可以先回顾一 …
