Query: RingFed: Reducing Communication Costs in Federated Learning on Non-IID
  Data   Federated learning is a widely used distributed deep learning framework that
protects the privacy of each client by exchanging model parameters rather than
raw data. However, federated learning suffers from high communication costs, as
a considerable number of model parameters need to be transmitted many times
during the training process, making the approach inefficient, especially when
the communication network bandwidth is limited. This article proposes RingFed,
a novel framework to reduce communication overhead during the training process
of federated learning. Rather than transmitting parameters between the center
server and each client, as in original federated learning, in the proposed
RingFed, the updated parameters are transmitted between each client in turn,
and only the final result is transmitted to the central server, thereby
reducing the communication overhead substantially. After several local updates,
clients first send their parameters to another proximal client, not to the
center server directly, to preaggregate. Experiments on two different public
datasets show that RingFed has fast convergence, high model accuracy, and low
communication cost.
