Latest Patents
Lei Cai holds a patent for "Structural graph neural networks for suspicious event detection." This patent describes a computer-implemented method for graph structure-based anomaly detection on a dynamic graph. The method involves detecting anomalous edges in the dynamic graph by learning graph structure changes concerning target edges evaluated over a given time window. The target edges correspond to specific timestamps. Additionally, the method predicts the category of each target edge as either anomalous or non-anomalous based on the graph structure changes. It also includes controlling a hardware-based device to prevent impending failures in response to the category of at least one of the target edges. This innovative technology has the potential to significantly improve the reliability of systems that rely on dynamic graph data.
