提议的 GCNN 是在 TensorFlow 中用 Python 实现的。 所有代码均在 GPL 许可下发布,并通过 GitHub (GitHub - XiongfengYan/gcnn: A graph convolutional neural network for classification of building patterns using spatial vector data) 分发。 本节描述了在大型建筑数据集上进行的一系列实验,以测试所提出方法的...
借鉴 GraphX 等思路,出现一些不依赖邻接矩阵(或是屏蔽了邻接矩阵细节的)的消息聚合库,比较有名的有 PyG(比较早,实现多)和 DGL(比较新,易上手)。在这些库中,节点可以发出信息,并接受周围节点的信息,显式地完成消息聚合。在这种情况下,越来越多...
DialogueGCN: A Graph Convolutional Neural Network for Emotion Recognition in Conversation 对话GCN:一个用于对话情感识别的图卷积神经网络 出处:EMNLP 2019 Abstract 会话中的情感识别(Emotion recognition in conversation,ERC)近来因在医疗、教育、人力资源等领域的广泛应用而受到研究者的广泛关注。本文提出了对话图卷积...
2、时间关系:交通流随时间动态变化,主要表现在周期性和趋势上;现有的交通状况被前一刻的交通状况影响。 现存交通预测方法缺陷:一些交通预测方法(ARIMA、Kalman filtering model,etc)只关注了交通状况的动态变化而忽视了空间关系,导致交通状态的变化不被道路网约束,同时一些模型尝试使用卷积神经网络进行空间性建模,但这些模...
Moreover, the graph convolutional network (GCN) is employed to extract the crucial interference features. Further, an end-to-end learning model is designed to implement the following resource allocation task to avoid the split with mismatched features and tasks. Finally, the deep reinforcement ...
The essential idea is to decompose a graph into\nfamilies of non-intersecting one dimensional (1D) paths, after which, we may\napply a 1D CNN along each family of paths. We demonstrate that the our method,\nwhich we call GraphFlow, is able to transfer CNN architectures to general\ngraphs...

What is a Graph Convolutional Network (GCN)? The majority of GNNs are Graph Convolutional Networks, and it is important to learn about them before jumping into a node classification tutorial. The convolution in GCN is the same as a convolution in convolutional neural networks. It multiplies neu...
GCN用于学习复杂的拓扑结构以捕获空间依赖性,而GRU用于学习交通数据的动态变化以捕获时间依赖性。T-GCN的代码:GitHub - lehaifeng/T-GCN: Temporal Graph Convolutional Network for Urban Traffic Flow Prediction Method 现有的流量预测方法:自回归综合移动平均(ARIMA)模型,SVM 和部分神经网络,考虑了交通的动态变化而...
