2.1. Abstract
①They proposed a graph attention networks (GATs), which is both suitable for inductive and transductive problems
②There is no need for special and costly matrix operation
③They test their model in Cora, Citeseer, Pubmed citation network datasets and proteinprotein interaction dataset
upfront adj.预付的;坦率的;诚实的;直爽的;预交的 adv.预付地,先期支付地
2.2. Introduction
①CNN has been widely used in translation, image classification, semantic segmentation. However, it can not be used in none-grid, i.e. irregular representation, such as social/telecommunication/biological networks, 3D meshes, brain connectomes. Thus, graph structure can describe these structures more accurately
②Early works adopted recursive neural networks to process directed acyclic graphs
③They introduced spectral and non-spectral methods of graph processing
④Allowing different sizes of input, attention mechanism has been sucessfully used in NLP
⑤Attention mechanism is able to parallelize neighbors, assign weights to neighbors and be used in inductive learning
acyclic adj.无环的;非循环的;非周期的;非环状的
