在上图中, 左边时传统的图聚类过程, 右边是本篇论文所研究的图聚类过程. Embedding表示的是图嵌入的过程, 通过编码器将高维紧凑的图矩阵降维到低维紧凑的矩阵. Clustering即是对降维后的数据进行聚类, 通常用k-means或者谱聚类等. 算法介绍: 具体算法: 图注意力编码器: 这里采用的Encoder是图注意力神经网络(GAT...
论文阅读02——《Attributed Graph Clustering: A Deep Attentional Embedding Approach》 Ideas: Model: Two-step DAEGC 图注意力自动编码器 自训练聚类模块 具体算法流程 Ideas: Two-step的图嵌入方法不是目标导向的,聚类效果不好,提出一种基于目标导向的属性图聚类框架。

it is necessary to utilize algorithms that are capable of handling such temporally evolving non-euclidean data. In this chapter, we present a novel dynamic graph embedding algorithm to handle this issue. In the rest of the chapter, we consider temporally evolving graphs as the non-euclidean data...
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...
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 ...

Graph inference models can use such embeddings and available additional features for several tasks, for example, visualization, clustering, and prediction of node labels, edges and edge labels1. State-of-the-art GRL algorithms, including, among others, methods based on matrix factorization, random ...
For one thing, unsupervised graph representation learning can be used as pre-training to generate feature vectors, then fused with other feature vectors and input to subsequent models; for another, supervised graph representation learning can be used as the embedding layer of the recommendation model...
