Split Federated Learning (SFL) combines federated learning and split learning.SFL partitions a neural network at a cut layer, with initial layers on clients and remaining layers on a training server.SFL-V1 maintains separate server-side models for each client, while SFL-V2 maintains a single shared model for all clients.Cut layer selection significantly affects the performance of SFL-V2, outperforming FedAvg on certain datasets.
