Embodiment 1
[0071] Embodiment 1: A device-edge-cloud architecture and an incentive method for hierarchical federated learning under complete information, including the following steps:
[0072] S1, based on the Stackelberg game to establish a three-tier game model between terminal devices, edge aggregators and cloud servers;
[0073] Such as figure 1 As shown, the cloud server, edge aggregator and terminal device constitute a hierarchical federated learning system, and the cloud server is the leader, task initiator, and model owner. The edge aggregator runs between the cloud server and multiple terminal devices as a medium for parameter aggregation. The collection of all terminal devices participating in model training adopts Represents, and each terminal device n maintains a data set χ n , x n is the data set χ contributed by terminal device n participating in model training n The amount of data contribution, that is, the strategy of terminal device n. if x n =0, indicating that ...
Embodiment 2
[0161] Embodiment 2: A device-edge-cloud architecture and an incentive system for hierarchical federated learning under complete information, including a cloud server connected to several edge aggregators, and each edge aggregator is connected to several terminal devices , and the cloud server is equipped with a power data learning model based on a federated learning algorithm. The edge aggregator is provided with a first revenue distribution module for distributing remuneration to the connected terminal equipment and a strategy formulation module for evaluating the data contribution of the terminal equipment, and the cloud server is provided with a module for sending the edge aggregator The second revenue distribution module for distributing rewards. During terminal device training, the first revenue distribution module distributes economic benefits to corresponding terminal devices according to the data contribution amount of the terminal device and the data quality of the co...
