Latest Patents

Zhang is associated with 1 patent: “Reservoir Area Water Bloom Rapid Monitoring Method and Device Based on Unmanned Aerial Vehicle Swarm Coordination.” The invention uses local-update quantification in a federated-learning system to reduce communication between UAVs and a central server while maintaining the accuracy of the monitoring model. It defines a loss-function queue for each UAV and uses the relationship between historical and current loss functions to quantify model updates. The approach is designed to ease the challenge of uploading large volumes of UAV imagery, reduce communication demands, and improve model convergence by limiting frequent communication.
