Rendering Wireless Environments Useful for Gradient Estimators: A Zero-Order Stochastic Federated Learning Method

no code implementations30 Jan 2024 Elissa Mhanna, Mohamad Assaad

By utilizing a communication-efficient framework, we propose a novel zero-order (ZO) method with a one-point gradient estimator that harnesses the nature of the wireless communication channel without requiring the knowledge of the channel state coefficient.

Zero-Order One-Point Estimate with Distributed Stochastic Gradient-Tracking Technique

no code implementations11 Oct 2022 Elissa Mhanna, Mohamad Assaad

We analyze the convergence of this novel technique for smooth and convex objectives using stochastic approximation tools, and we prove that it converges almost surely to the optimum.

A Novel Algorithm to Report CSI in MIMO-Based Wireless Networks

no code implementations1 Apr 2021 Muhammad Karam Shehzad, Luca Rose, Mohamad Assaad

Besides, in the immobile radio channel, feedback can be eliminated, which brings the benefit of further reducing the OTA overhead.

Dealing with CSI Compression to Reduce Losses and Overhead: An Artificial Intelligence Approach

no code implementations1 Apr 2021 Muhammad Karam Shehzad, Luca Rose, Mohamad Assaad

The proposed scheme enhances the CSI compression, which is done at the mobile terminal (MT), along with accurate recovery of estimated CSI at the BS.

Semantic Communications in Networked Systems: A Data Significance Perspective

Distributed Power Control for Large Energy Harvesting Networks: A Multi-Agent Deep Reinforcement Learning Approach

no code implementations1 Apr 2019 Mohit K. Sharma, Alessio Zappone, Mohamad Assaad, Merouane Debbah, Spyridon Vassilaras

In the proposed framework, we model the online power control problem as a discrete-time mean-field game (MFG), and analytically show that the MFG has a unique stationary solution.
