How convolution neural networks work CNN Convolution neural networks or con nets or CNNS can do some pretty cool things。If you feed them a bunch of pictures of faces for instance, don’t learn some basic things like edges and dots b... ...
通过GIN 学习的节点嵌入可以直接用于节点分类问题以及链路预测问题,但对于图分类问题,我们提出了以下方法:通过节点的嵌入构造整个图的嵌入。一般我们会把这个过程称为Graph Readout。 Graph Readout 的一个重要因素是:随着迭代(聚合)次数增加,对应于子树结构的节点表征会变得更加精细以及覆盖范围更广。因此足够的迭代次数...
论文解读——How Powerful are Graph Neural Networks 这个题目直译过来是“图神经网络有多强大”,我一开始以为是类似综述的论文,讲GNN的内容、用途、优势等,但是最后发现发现侧重点是在 理论分析GNN的强大,比如说理论上强大的上界、达到这… 狂野神龙鼠 The Expressive Power of Graph Neural Networks: A Survey 两...
Graph Neural Networks (GNNs) have known an important and fast development in the last decade, with many theoretical and practical innovations. Their main feature is the capability of processing graph structured data with minimal loss of structural information. This makes GNNs the ideal family of ...
