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.

Boosting Federated Learning in Resource-Constrained Networks

no code implementations21 Oct 2021 Mohamed Yassine Boukhari, Akash Dhasade, Anne-Marie Kermarrec, Rafael Pires, Othmane Safsafi, Rishi Sharma

GeL enables constrained edge devices to perform additional learning through guessed updates on top of gradient-based steps.

WideCaps: A Wide Attention based Capsule Network for Image Classification

no code implementations8 Aug 2021 S J Pawan, Rishi Sharma, Hemanth Sai Ram Reddy, M Vani, Jeny Rajan

However, on the datasets involving complex foreground and background regions such as CIFAR-10, the performance of the capsule network is sub-optimal due to its naive data routing policy and incompetence towards extracting complex features.
