然后对于每个view和新图来说,同样的节点作为正样本,不同的节点作为负样本优化对比损失InfoNCE。 10. WWW2023 |SEGSL|SE-GSL: A General and Effective Graph Structure Learning Framework through Structural Entropy Optimization 首先基于节点特征构建了一个kNN图,和原图一起fusion一下之后得到一个新的图。根据文中的...
不过换句话说,其实将这个过程理解为“curriculum learning应用于graph structure learning”难免有些牵强,因为图结构的学习是一个在训练迭代过程中稳定学习的部分。 所以将curriculum learning应用于graph structure learning这个方面,还有很多很多空间可以让我们去思考。对于这方面,我也有一些初步的思考,比如之前我说的构图时...

Deep learningGraph convolutional neural networksGraph structure learningChangeable kernel sizesGraph convolutional neural networks have aroused more and more attentions on account of the ability to handle the graph-structured data defined on irregular or non-Euclidean domains. Different from the data defined...
graph structure learning aims to discover useful graph structures from data, which can help solve the above issue. This chapter attempts to provide a comprehensive introduction of graph structure learning through the lens of both traditional machine learning and GNNs. After reading this chapter, ...

首先,他们使用structure2vec来实现顶点嵌入,然后将其输入Q-learning模块进行决策。这项工作也证明了GNN的嵌入能力。Nowak等人[184]专注于二次分配问题,即测量两个图的相似度。GNN模型学习了每个图的顶点嵌入,并使用注意力机制来匹配这两个图。 8. 开放性问题...
