Universal Auto-encoder Framework for MIMO CSI Feedback

no code implementations1 Mar 2024 Jinhyun So, HyukJoon Kwon

Existing auto-encoder (AE)-based channel state information (CSI) frameworks have focused on a specific configuration of user equipment (UE) and base station (BS), and thus the input and output sizes of the AE are fixed.

FedSpace: An Efficient Federated Learning Framework at Satellites and Ground Stations

no code implementations2 Feb 2022 Jinhyun So, Kevin Hsieh, Behnaz Arzani, Shadi Noghabi, Salman Avestimehr, Ranveer Chandra

To address these challenges, we leverage Federated Learning (FL), where ground stations and satellites collaboratively train a global ML model without sharing the captured images on the satellites.

Secure Aggregation for Buffered Asynchronous Federated Learning

no code implementations5 Oct 2021 Jinhyun So, Ramy E. Ali, Başak Güler, A. Salman Avestimehr

A buffered asynchronous training protocol known as FedBuff has been proposed recently which bridges the gap between synchronous and asynchronous training to mitigate stragglers and to also ensure privacy simultaneously.

LightSecAgg: a Lightweight and Versatile Design for Secure Aggregation in Federated Learning

no code implementations29 Sep 2021 Jinhyun So, Chaoyang He, Chien-Sheng Yang, Songze Li, Qian Yu, Ramy E. Ali, Basak Guler, Salman Avestimehr

We also demonstrate that, unlike existing schemes, LightSecAgg can be applied to secure aggregation in the asynchronous FL setting.

Securing Secure Aggregation: Mitigating Multi-Round Privacy Leakage in Federated Learning

no code implementations7 Jun 2021 Jinhyun So, Ramy E. Ali, Basak Guler, Jiantao Jiao, Salman Avestimehr

In fact, we show that the conventional random user selection strategies in FL lead to leaking users' individual models within number of rounds that is linear in the number of users.

On Polynomial Approximations for Privacy-Preserving and Verifiable ReLU Networks

no code implementations11 Nov 2020 Ramy E. Ali, Jinhyun So, A. Salman Avestimehr

In this work, we empirically show that the square function is not the best degree-2 polynomial that can replace the ReLU function even when restricting the polynomials to have integer coefficients.

A Scalable Approach for Privacy-Preserving Collaborative Machine Learning

no code implementations NeurIPS 2020 Jinhyun So, Basak Guler, A. Salman Avestimehr

We consider a collaborative learning scenario in which multiple data-owners wish to jointly train a logistic regression model, while keeping their individual datasets private from the other parties.

Byzantine-Resilient Secure Federated Learning

no code implementations21 Jul 2020 Jinhyun So, Basak Guler, A. Salman Avestimehr

This presents a major challenge for the resilience of the model against adversarial (Byzantine) users, who can manipulate the global model by modifying their local models or datasets.

Turbo-Aggregate: Breaking the Quadratic Aggregation Barrier in Secure Federated Learning

no code implementations11 Feb 2020 Jinhyun So, Basak Guler, A. Salman Avestimehr

A major bottleneck in scaling federated learning to a large number of users is the overhead of secure model aggregation across many users.
