GitHub is where people build software. More than 100 million people use GitHub to discover, fork, and contribute to over 420 million projects.
三种图神经网络算法:GraphSAGE, GCN 和 GAT GNN 处理图数据的方式还是很符合直觉的,基本沿袭了 CNN 的思路:每个神经元只看局部信息,通过层层汇聚掌握全貌。 GitHub 项目地址:graph-embedding 本文做了什么: 对GraphSAGE 的简单实现做逐行注释 在Docker 环境运行 GraphSAGE 的原版示例 用PyG 实现了 GCN 和 GAT 为运...
其实看懂了gcn之后,graphsage基本上也能看懂,graphsage一直强调自己是归纳式的,gcn是直推式的,其实gcn稍微改动一下就可以变成归纳式的,所以其实硬说gcn是直推式的其实对于应用来说帮助不大。 从代码实现上来看, https://github.com/dmlc/dgl/blob/master/python/dgl/nn/pytorch/conv/graphconv.pygithub.com/...

代码:https://github.com/williamleif/graphsage-simple/ 此文提出的方法叫GraphSAGE,针对的问题是之前的网络表示学习的transductive,从而提出了一个inductive的GraphSAGE算法。GraphSAGE同时利用节点特征信息和结构信息得到Graph Embedding的映射,相比之前的方法,之前都是保存了映射后的结果,而GraphSAGE保存了生成embedding的映射...
