An Anomaly Event Detection Method Based on GNN Algorithm for Multi-data Sources

Abstract

Anomaly event detection is crucial for critical infrastructure security(transportation system, social-ecological sector, insurance service, government sector etc.) due to its ability to reveal and address the potential cyber-threats in advance by analysing the data(messages, microblogs, logs etc.) from digital systems and networks. However, the convenience and applicability of smart devices and the maturity of connected technology make the social anomaly events data multi-source and dynamic, which result in the inadaptability for multi-source data detection and thus affect the critical infrastructure security. To effectively address the proposed problems, in this paper, we design a novel anomaly detection method based on multi-source data. First, we leverage spectral clustering algorithm for feature extraction and fusion of multiple data sources. Second, by harnessing the power of deep graph neural network(Deep-GNN), we perform a fine-gained anomaly social event detection, revealing the threatening events and guarantee the critical infrastructure security. Experimental results demonstrate that our framework outperforms other baseline anomaly event detection methods and shows high tracking accuracy, strong robustness and stability.

Urban Landscaping Landscape Design and Maintenance Management Method Based on Multisource Big Data Fusion

“…Due to the particularity of some diseases, the number of patients is relatively small, and the amount of related data is also small [ 11 ]. Dana Lahat et al proposed a multimodal data fusion method to fuse datasets obtained by different means [ 12 ]. D. L. Hall compares multisensor data fusion with single sensor data fusion and believes that multisensor data fusion will have more advantages in data accuracy and practical application.…”
