no code implementations15 May 2024 Federica Fieramosca, Vittorio Rampa, Michele D'Amico, Stefano Savazzi

Recently, proposals of human-sensing-based services for cellular and local area networks have brought indoor localization to the attention of several research groups.

Indoor Localization

Physics-informed generative neural networks for RF propagation prediction with application to indoor body perception

no code implementations3 May 2024 Federica Fieramosca, Vittorio Rampa, Michele D'Amico, Stefano Savazzi

Electromagnetic (EM) body models designed to predict Radio-Frequency (RF) propagation are time-consuming methods which prevent their adoption in strict real-time computational imaging problems, such as human body localization and sensing.

An EM Body Model for Device-Free Localization with Multiple Antenna Receivers: A First Study

no code implementations2 May 2024 Vittorio Rampa, Federica Fieramosca, Stefano Savazzi, Michele D'Amico

By exploiting the Integrated Sensing and Communication paradigm, DFL networks employ Radio Frequency (RF) nodes to measure the excess attenuation introduced by the subjects (i. e., human bodies) moving inside the monitored area, and to estimate their positions and movements.

A physics-informed generative model for passive radio-frequency sensing

no code implementations6 Oct 2023 Stefano Savazzi, Federica Fieramosca, Sanaz Kianoush, Vittorio Rampa, Michele D'Amico

Electromagnetic (EM) body models predict the impact of human presence and motions on the Radio-Frequency (RF) stray radiation received by wireless devices nearby.

On the Energy and Communication Efficiency Tradeoffs in Federated and Multi-Task Learning

no code implementations2 Dec 2022 Stefano Savazzi, Vittorio Rampa, Sanaz Kianoush, Mehdi Bennis

The MTL process is carried out in two stages: the optimization of a meta-model that can be quickly adapted to learn new tasks, and a task-specific model adaptation stage where the learned meta-model is transferred to agents and tailored for a specific task.
