FedPerm: Private and Robust Federated Learning by Parameter Permutation

no code implementations16 Aug 2022 Hamid Mozaffari, Virendra J. Marathe, Dave Dice

We present FedPerm, a new FL algorithm that addresses both these problems by combining a novel intra-model parameter shuffling technique that amplifies data privacy, with Private Information Retrieval (PIR) based techniques that permit cryptographic aggregation of clients' model updates.

Subject Granular Differential Privacy in Federated Learning

no code implementations7 Jun 2022 Virendra J. Marathe, Pallika Kanani, Daniel W. Peterson, Guy Steele Jr

We formally prove the subject level DP guarantee for our algorithms, and also show their effect on model utility loss.

Subject Membership Inference Attacks in Federated Learning

no code implementations7 Jun 2022 Anshuman Suri, Pallika Kanani, Virendra J. Marathe, Daniel W. Peterson

Using these attacks, we estimate subject membership inference risk on real-world data for single-party models as well as FL scenarios.

Private Cross-Silo Federated Learning for Extracting Vaccine Adverse Event Mentions

no code implementations12 Mar 2021 Pallika Kanani, Virendra J. Marathe, Daniel Peterson, Rave Harpaz, Steve Bright

Users can indirectly contribute to, and directly benefit from a much larger aggregate data corpus used to train the global model.

Microsecond Consensus for Microsecond Applications

1 code implementation13 Oct 2020 Marcos K. Aguilera, Naama Ben-David, Rachid Guerraoui, Virendra J. Marathe, Athanasios Xygkis, Igor Zablotchi

We propose Mu, a system that takes less than 1. 3 microseconds to replicate a (small) request in memory, and less than a millisecond to fail-over the system - this cuts the replication and fail-over latencies of the prior systems by at least 61% and 90%.

Efficient Multi-word Compare and Swap

1 code implementation6 Aug 2020 Rachid Guerraoui, Alex Kogan, Virendra J. Marathe, Igor Zablotchi

Then we present the first algorithm that requires k+1 CASes per call to k-CAS in the common uncontended case.

Private Federated Learning with Domain Adaptation

no code implementations13 Dec 2019 Daniel Peterson, Pallika Kanani, Virendra J. Marathe

Federated Learning (FL) is a distributed machine learning (ML) paradigm that enables multiple parties to jointly re-train a shared model without sharing their data with any other parties, offering advantages in both scale and privacy.
