A Byzantine fault is any fault presenting different symptoms to different observers. A Byzantine failure is the loss of a system service due to a Byzantine fault in systems that require consensus among distributed nodes. The objective of Byzantine fault tolerance is to be able to defend against failures of system components with or without symptoms that prevent other components of the system from reachi… Webcan fail the whole learning system and causing the classical distributed SGD algorithm to diverge. In light of the vulnera-bility of the traditional SGD-based optimization algorithms, there have been strong interests in designing robust SGD-type algorithms that are resilient to Byzantine attacks in distributed learning.
