Intelligent detection method based on graph neural network
PendingCN110415215AImprove efficiency and accuracyReduce interventionImage enhancementImage analysisPrediction systemNetwork model
The invention provides an intelligent detection method based on a graph neural network. The intelligent detection method comprises the following steps of collecting data, preprocessing the data, building a network model, carrying out pre-training and transfer learning, carrying out predicting and performing casual inspection verification to perfect a whole prediction system. Compared with manual detection, the method has the advantages that the component detection accuracy and efficiency are improved, the interference of human factors on detection is reduced, and the labor cost and the detection cost are reduced. Compared with a traditional machine learning method, the method has the advantages that the graph neural network does not require that the composition form of the data must have agood spatial relationship, that is to say, the graph neural network has a neatly arranged matrix form, and the feature that the graph neural network can accept unstructured input significantly improves the expression ability of the model. Compared with a convolutional neural network method, the graph neural network can better learn the logic relationship of each element, so that the generalization ability of the model is improved. In the learning process of the network, each node is responsible for spreading own information and integrating information of neighbor nodes, so that the logic normal form of data is learned and mastered.
