Completion Time Minimization of Fog-RAN-Assisted Federated Learning With Rate-Splitting Transmission
نویسندگان
چکیده
This work studies federated learning (FL) over a fog radio access network, in which multiple internet-of-things (IoT) devices cooperatively learn shared machine model by communicating with cloud server (CS) through distributed points (APs). Under the assumption that fronthaul links connecting APs to CS have finite capacity, rate-splitting transmission at IoT (IDs) is proposed enables hybrid edge and decoding of split uplink messages. The problem completion time minimization for FL tackled optimizing quantization strategies along training hyperparameters such as precision iteration numbers. Numerical results show achieves notable gains benchmark schemes rely solely on or decoding.

This paper investigates the two-way relay transmission over orthogonal frequency division multiplexing (OFDM) channels using digital network coding. For a given amount of data to be transmitted, we formulate an optimization problem to minimize the total transmission completion time by jointly allocating the power and assigning the subcarriers under individual power constraints. Due to the diffi...
