Query: Device Scheduling with Fast Convergence for Wireless Federated Learning   Owing to the increasing need for massive data analysis and model training at
the network edge, as well as the rising concerns about the data privacy, a new
distributed training framework called federated learning (FL) has emerged. In
each iteration of FL (called round), the edge devices update local models based
on their own data and contribute to the global training by uploading the model
updates via wireless channels. Due to the limited spectrum resources, only a
portion of the devices can be scheduled in each round. While most of the
existing work on scheduling focuses on the convergence of FL w.r.t. rounds, the
convergence performance under a total training time budget is not yet explored.
In this paper, a joint bandwidth allocation and scheduling problem is
formulated to capture the long-term convergence performance of FL, and is
solved by being decoupled into two sub-problems. For the bandwidth allocation
sub-problem, the derived optimal solution suggests to allocate more bandwidth
to the devices with worse channel conditions or weaker computation
capabilities. For the device scheduling sub-problem, by revealing the trade-off
between the number of rounds required to attain a certain model accuracy and
the latency per round, a greedy policy is inspired, that continuously selects
the device that consumes the least time in model updating until achieving a
good trade-off between the learning efficiency and latency per round. The
experiments show that the proposed policy outperforms other state-of-the-art
scheduling policies, with the best achievable model accuracy under training
time budgets.
