因此,可以预先计算并索引大型数据库中的图嵌入,这样就能用快速的最近邻搜索数据结构(如 k-d 树) 或局部敏感哈希算法 (Gionis et al., 1999) 执行高效的检索。 研究者进一步扩展 GNN,提出新型图匹配网络(Graph Matching Networks,GMN)来执行相似性学习。GMN 没有单独计算每个图的图表征,它通过跨图注意力机制计算...

node encoder network, the last element is the size of the node outputs. If not provided, node features will pass through as is. edge_hidden_sizes: if provided should be a list of ints, hidden sizes of edge encoder network, the last element is the size of the edge outptus. If not ...
In this paper we propose a new convolution neural network architecture, defined directly into graph space. Convolution and pooling operators are defined in graph domain. We show its usability in a back-propagation context. Experimental results show that our model performance is at state of the art...
Neural Graph Matching Network: Learning Lawler's Quadratic Assignment Problem with Extension to Hypergraph and Multiple-graph Matching 如上,主要贡献有: 针对QAP做了端对端的机器学习 扩展到了 hyper-graph matching 扩展到了 multi-graph matching 什么是 Lawler's QAP 呢?就是针对提取后的特征矩阵直接处理,...

而就 2020的情况来看,这个趋势还在不断扩大。总之,Graph Neural Network (简称“GNN”)在2019- 2020年之间,力压 Deep Learning、GAN等,成为各大顶会的增长热词,且GNN在各个领域越来越受到欢迎,包括社交网络、知识图谱、推荐系统,甚...
推荐系统的发展可分为三个阶段:shallow models -> neural network-based models -> GNN models。其中: shallow models 最早的推荐系统是利用协同过滤(Collaborative Filtering,CF)来计算user和item之间的相似度。后续在此基础上又提出了matrix factorization(MF)、factorization machine等方法。
Local feature matchingGraph matchingDeep learning for sets3. The SuperGlue Architecture3.0.1 Motivation 在图像匹配问题中,可以利用世界的一些规律:3D世界在很大程度上是平滑的,有时是平面的,如果场景是静态的,则给定图像对的所有对应关系都来自单个极线变换,并且某些姿势比其他姿势更有可能。
