Covert Air–Ground Federated Learning With Pruning: Enabling by STAR-RIS

Federated learning (FL) can safeguard the data privacy for air-ground networks, while simultaneously transmitting and reflecting reconfigurable intelligent surface (STAR-RIS) can help further enhance its channel quality. However, the model exchanges in FL may be detected by wardens, and air-ground links increase this t...
