Cell-Free Multi-User MIMO Equalization via In-Context Learning

2 code implementations8 Apr 2024 Matteo Zecchin, Kai Yu, Osvaldo Simeone

In this work, we demonstrate that ICL can be also used to tackle the problem of multi-user equalization in cell-free MIMO systems with limited fronthaul capacity.

In-Context Learning for MIMO Equalization Using Transformer-Based Sequence Models

1 code implementation10 Nov 2023 Matteo Zecchin, Kai Yu, Osvaldo Simeone

In ICL, a decision on a new input is made via a direct mapping of the input and of a few examples from the given task, serving as the task's context, to the output variable.

User-Centric Federated Learning: Trading off Wireless Resources for Personalization

no code implementations25 Apr 2023 Mohamad Mestoukirdi, Matteo Zecchin, David Gesbert, Qianrui Li

Statistical heterogeneity across clients in a Federated Learning (FL) system increases the algorithm convergence time and reduces the generalization performance, resulting in a large communication overhead in return for a poor model.

Decentralized learning empowers wireless network devices to collaboratively train a machine learning (ML) model relying solely on device-to-device (D2D) communication.

Asynchronous Decentralized Learning over Unreliable Wireless Networks

no code implementations2 Feb 2022 Eunjeong Jeong, Matteo Zecchin, Marios Kountouris

Decentralized learning enables edge users to collaboratively train models by exchanging information via device-to-device communication, yet prior works have been limited to wireless networks with fixed topologies and reliable workers.

User-Centric Federated Learning

no code implementations19 Oct 2021 Mohamad Mestoukirdi, Matteo Zecchin, David Gesbert, Qianrui Li, Nicolas Gresset

Data heterogeneity across participating devices poses one of the main challenges in federated learning as it has been shown to greatly hamper its convergence time and generalization capabilities.
