1. 简介 Graph Embedding指把graph转化为低维vector,使得Graph上的问题可以用vector上的方法处理。 这样做的意义在于: 低维vector形式的算法相比原graph形式的算法所需算力更小 低维vector形式的算法更多更强 我从一篇综述 A Comprehensive Survey of Graph Embedding: Problems, Techniques and Applicationsarxi...
这篇博文主要是对论文“Deep Clustering by Gaussian Mixture Variational Autoencoders with Graph Embedding”的整理总结,这篇文章将图嵌入与概率深度高斯混合模型相结合,使网络学习到符合全局模型和局部结构约束的强大特征表示。将样本作为图上的节点,并最小化它们的后验分布之间的加权距离,在这里使用Jenson-Shannon散度...

GAT is the architecture that our model mainly based, it computes representation of each node by combining its neighborhoods vectors in an adaptive way with adjustable attention weights for different neighborhoods. ARVGA uses a variational graph autoencoder to learn embedding and perform the link ...
To well exploit cluster structure, inspired by these insight analysis, we propose a nodes clustering method, namely, Graph Embedding Clustering: Graph Attention Auto-encoder With Cluster-Specificity Distribution (GEC-CSD). Specifically, to make the decoder part learnable, node attributes reconstruction ...
