Gophormer是一种图神经网络(GNN)模型,专门用于节点分类任务。它结合了Transformer架构和ego-graph的概念,旨在克服传统GNN在处理大型图时的可扩展性问题和长距离依赖捕获能力不足的局限。Gophormer通过为每个节点生成一个ego-graph(自我图),并使用Transformer模型对这些ego-graphs进行编码,来学习节点的表示。 2. Ego-Gra...

Based on this review and our experiments, we propose our own method which leverages the social graph's topology and differences in egographs of legitimate and fake user accounts to improve identification of the latter. We evaluate our approach against other common approaches on a real-world ...
本文实际上也没有解决这个问题,因为跨帧的obj已经通过CAIM(Class Agnostic Instance Mask)的辅助解决了,相当于对于每一帧的点云$P_i$,都只需要使用PointNet抽取特征后,根据CAIM映射一下即可得到。 之后本文的内容就变的非常简单了,就是提出了一个Local Graph Reasoning和Global Graph Reasoning的模块,进行了每帧的SG...
We select 13 well-known network measures, especially those concerned with ego graphs. We form eight feature subsets and then assess their performance using unsupervised clustering techniques to discover distinguishing ego-centric patterns. From clustering analysis, we discover that eight distinct ...

This is the repo for "Distributed, Egocentric Representations of Graphs for Detecting Critical Structures", Ruo-Chun Tzeng, Shan-Hung Wu, In Proceedings of ICML 2019.slides In the paper, we proposed Ego-Convolution layer, which keeps the nice properties of Convolution layer to the graph ...
may be interested in global network-wide analysis (e.g., centrality analysis, community detection) where the properties of the entire network are of interest, or local ego-centric analysis where the focus is on studying the properties of nodes (egos) by analyzing their neighborhood sub graphs....
In this paper, we propose an effective and also efficient method for generating node embeddings in graphs that employs a restricted number of permutations over the immediate neighborhood of a node as context to generate its representation, thus ego-centric representations. We present a thorough ...
