2. Up until now, our GNN is based on a neighborhood-based pooling operation. There are some graph concepts that are harder to express in this way, for example a linear graph path (a connected chain of nodes). Designing new mechanisms in which graph information can be extracted, executed a...

The learnable functions are mostly neural networks and eventually determine the performance characteristics of the GNN, both in prediction accuracy and computational cost. Figure 1a shows a schematic of the message passing scheme for the example of a molecular graph. Message passing can also be ...
处理的数据特征:具有规则的空间结构(Euclidean domains),都可以采用一维或者二维的矩阵描述。(Convolutional neural network (CNN) gains great success on Euclidean data, e.g., image, text, audio, and video)。 什么是卷积:卷积即固定数量邻域结点排序后,与相同数量的卷积核参数相乘求和。
We solve this problem in a more "industrial" way (as shown in Figure 6 below), the framework is divided into two layers: basic components and process components. The basic components focus on a single function. For example, the graph data component only maintains the graph data structure in...
This example shows how to detect anomalies in multivariate time series data using a graph neural network (GNN). To detect anomalies or anomalous variables/channels in a multivariate time series data, you can use Graph Deviation Network (GDN) [1]. GDN is a type of GNN that learns...

GNNs are unique in two other ways: They use sparse math, and the models typically only have two or three layers. Other AI models generally use dense math and have hundreds of neural-network layers. A GNN pipeline has a graph as an input and predictions as outputs. ...
microstructure data can be directly used as the model input. For example, each voxel of a 3D microstructure image can be associated with a vector that stores the physical features (e.g., crystal orientation12) in that voxel. Convolutional neural network (CNN) can then be used to obtain low...
