but also their microstructures which typically refer to the size (nm–μm), shape, orientation, and adjacency relation of the grains. Here, we develop a graph neural network1,2based machine learning
Networks of spatially distributed radiofrequency identification sensors could be used to collect data in wearable or implantable biomedical applications. However, the development of scalable networks remains challenging. Here we report a wireless radiofr
Here, we will present an overview of graph neural networks from the viewpoint of aggregation, focussing on the aspects most relevant in that context. 5.2.1 Graph representation Let G=(V,E) denote a graph, where V and E are the sets of nodes and edges respectively. Each node v∈V is ...
GNN is powerful in transductive learning,e.g., node classification under graph data. transductive learning直推式学习、inductive learning归纳式学习。 transductive learning:给定训练数据包含了目标域数据,要求训练一个对目标数据有最小误差的模型。(半监督学习的含义) ...

The adjective "neural" refers to a neuron, while "network" refers to a graph-like structure. The term "artificial neural network" describes computer processes based on the basic concept of biological neural networks. ANN is made up of interconnected artificial neurons that are programmed to ...
Graph neural networks A graphical neural network (GNN) is a type of neural network that was designed to process non-Euclidean data structures such as graphs (Zhou et al., 2020). GNNs can be directly applied to graphs and provide an efficient method for executing node classification, unsupervise...
