Beyond Noise: Privacy-Preserving Decentralized Learning with Virtual Nodes

no code implementations15 Apr 2024 Sayan Biswas, Mathieu Even, Anne-Marie Kermarrec, Laurent Massoulie, Rafael Pires, Rishi Sharma, Martijn de Vos

We theoretically prove the convergence of Shatter and provide a formal analysis demonstrating how Shatter reduces the efficacy of attacks compared to when exchanging full models between participating nodes.

Epidemic Learning: Boosting Decentralized Learning with Randomized Communication

1 code implementation NeurIPS 2023 Martijn de Vos, Sadegh Farhadkhani, Rachid Guerraoui, Anne-Marie Kermarrec, Rafael Pires, Rishi Sharma

We present Epidemic Learning (EL), a simple yet powerful decentralized learning (DL) algorithm that leverages changing communication topologies to achieve faster model convergence compared to conventional DL approaches.

Get More for Less in Decentralized Learning Systems

1 code implementation7 Jun 2023 Akash Dhasade, Anne-Marie Kermarrec, Rafael Pires, Rishi Sharma, Milos Vujasinovic, Jeffrey Wigger

Decentralized learning (DL) systems have been gaining popularity because they avoid raw data sharing by communicating only model parameters, hence preserving data confidentiality.

Decentralized Learning Made Easy with DecentralizePy

1 code implementation17 Apr 2023 Akash Dhasade, Anne-Marie Kermarrec, Rafael Pires, Rishi Sharma, Milos Vujasinovic

Decentralized learning (DL) has gained prominence for its potential benefits in terms of scalability, privacy, and fault tolerance.

TEE-based decentralized recommender systems: The raw data sharing redemption

1 code implementation23 Feb 2022 Akash Dhasade, Nevena Dresevic, Anne-Marie Kermarrec, Rafael Pires

We analyze the impact of raw data sharing in both deep neural network (DNN) and matrix factorization (MF) recommenders and showcase the benefits of trusted environments in a full-fledged implementation of REX.
