Coded Matrix Computations for D2D-enabled Linearized Federated Learning

no code implementations23 Feb 2023 Anindya Bijoy Das, Aditya Ramamoorthy, David J. Love, Christopher G. Brinton

Federated learning (FL) is a popular technique for training a global model on data distributed across client devices.

Detection and Mitigation of Byzantine Attacks in Distributed Training

1 code implementation17 Aug 2022 Konstantinos Konstantinidis, Namrata Vaswani, Aditya Ramamoorthy

For strong attacks, we demonstrate a reduction in the fraction of distorted gradients ranging from 16%-99% as compared to the prior state-of-the-art.

Aspis: Robust Detection for Distributed Learning

no code implementations5 Aug 2021 Konstantinos Konstantinidis, Aditya Ramamoorthy

We prove the Byzantine resilience and detection guarantees of Aspis under weak and strong attacks and extensively evaluate the system on various large-scale training scenarios.

ByzShield: An Efficient and Robust System for Distributed Training

1 code implementation10 Oct 2020 Konstantinos Konstantinidis, Aditya Ramamoorthy

Our numerical experiments indicate over a 36% reduction on average in the fraction of corrupted gradients compared to the state of the art.

Federated Over-Air Subspace Tracking from Incomplete and Corrupted Data

1 code implementation28 Feb 2020 Praneeth Narayanamurthy, Namrata Vaswani, Aditya Ramamoorthy

In this work we study the problem of Subspace Tracking with missing data (ST-miss) and outliers (Robust ST-miss).

Resolvable Designs for Speeding up Distributed Computing

no code implementations14 Aug 2019 Konstantinos Konstantinidis, Aditya Ramamoorthy

In this work, we show that a class of combinatorial structures called resolvable designs can be used to develop efficient coded distributed computing schemes for both the single and multiple job scenarios considered in prior work.

Random Convolutional Coding for Robust and Straggler Resilient Distributed Matrix Computation

1 code implementation18 Jul 2019 Anindya B. Das, Aditya Ramamoorthy, Namrata Vaswani

Distributed matrix computations (matrix-vector and matrix-matrix multiplications) are at the heart of several tasks within the machine learning pipeline.

CAMR: Coded Aggregated MapReduce

no code implementations22 Jan 2019 Konstantinos Konstantinidis, Aditya Ramamoorthy

Many big data algorithms executed on MapReduce-like systems have a shuffle phase that often dominates the overall job execution time.

Erasure coding for distributed matrix multiplication for matrices with bounded entries

no code implementations6 Nov 2018 Li Tang, Konstantinos Konstantinidis, Aditya Ramamoorthy

We demonstrate a tradeoff between the assumed absolute value bounds on the matrix entries and the recovery threshold.

Leveraging Coding Techniques for Speeding up Distributed Computing

no code implementations8 Feb 2018 Konstantinos Konstantinidis, Aditya Ramamoorthy

Appropriate interpretation of resolvable designs can allow for the development of coded distributed computing schemes where the splitting levels are exponentially lower than prior work.
