Interactive Byzantine-Resilient Gradient Coding for General Data Assignments
Shreyas Jain, Luis Maßny, Christoph Hofmeister +2
We tackle the problem of Byzantine errors in distributed gradient descent within the Byzantine-resilient gradient coding framework. Our proposed solution can recover the exact full…

Byzantine-Resilient Gradient Coding through Local Gradient Computations
Christoph Hofmeister, Luis Maßny, Eitan Yaakobi +1
We consider gradient coding in the presence of an adversary controlling so-called malicious workers trying to corrupt the computations. Previous works propose the use of MDS codes…
