Convergence Time Optimization for Federated Learning Over Wireless Networks
TL;DR: In this paper, the convergence time of federated learning (FL) over a realistic wireless network is studied, and a probabilistic user selection scheme is proposed such that the BS is connected to the users whose local FL models have significant effects on the global FL model with high probabilities.

TL;DR: Simulation results show that the proposed scheme achieves up to 33\% and 68\% gains in terms of the energy efficiency in both single-user and multi-user cases compared to the conventional RIS scheme and amplify-and-forward relay scheme, respectively.

Convergence Time Optimization for Federated Learning over Wireless Networks
TL;DR: A probabilistic user selection scheme is proposed such that the BS is connected to the users whose local FL models have significant effects on the global FL model with high probabilities, which enables the BS to improve the global model, the FL convergence speed, and the training loss.

Distributed Multi-Agent Meta Learning for Trajectory Design in Wireless Drone Networks
TL;DR: A value decomposition based reinforcement learning (VDRL) solution coupled with a meta-training mechanism is proposed that allows the DBSs to dynamically learn their trajectories while generalizing their learning to unseen environments.

Energy-Efficient Wireless Communications with Distributed Reconfigurable Intelligent Surfaces
Zhaohui Yang,Mingzhe Chen,Walid Saad,Wei Xu,Mohammad Shikh-Bahaei,H. Vincent Poor,Shuguang Cui +6 more
TL;DR: In this paper, the problem of resource allocation for a wireless communication network with distributed reconfigurable intelligent surfaces (RISs) is posed as a joint optimization problem of transmit beamforming and RIS control, whose goal is to maximize the EE under minimum rate constraints of the users.
