图网络学习算法之——GGNN (Gated Graph Neural Network)
GGNN是一种基于 GRU 的经典的空间域message passing的模型。 message passing的通用框架共包含三部分操作:信息传递操作 (M),更新操作 (U),读取操作 (R)。 从如下公式中可以看出,节点v的t+1时刻的embedding m,由其当前时刻的embedding,以及其邻居节点的当前时刻embedding,和二者的交互的边信息所决定。 在全图的信息传递过程中,采用的是GRU的原理。 传播模型如下图所示,其中式 (1), h_v^1 为节点v的初始隐向量,为D维的向量,当节点输入 …

2016年9月9日 · We present a scalable approach for semi-supervised learning on graph-structured data that is based on an efficient variant of convolutional neural networks which operate directly on graphs. We motivate the choice of our convolutional architecture via a localized first-order approximation of spectral graph convolutions.

RPI-GGCN: Prediction of RNA-Protein Interaction Based on
Predicting RPI can guide the exploration of cellular biological functions, intervening in diseases, and designing drugs. Given this, this study proposes the RPI-gated graph convolutional network (RPI-GGCN) method for predicting RPI based on the gated graph convolutional neural network (GGCN) and co-regularized variational autoencoder (Co-VAE).
