Coding for Straggler Mitigation in Federated Learning [article]

Siddhartha Kumar, Reent Schlegel, Eirik Rosnes, Alexandre Graell i Amat
2022 arXiv   pre-print
The proposed scheme combines one-time padding to preserve privacy and gradient codes to yield resiliency against stragglers and consists of two phases.  ...  In the first phase, the devices share a one-time padded version of their local data with a subset of other devices.  ...  The main idea in [25] is that devices generate parity data, which is shared with the central server to facilitate the training and provide resilience against straggling devices.  ...

Although work proposes scalable BFT protocols that run on a larger number of committee nodes, their efficiency drops dramatically when only a small number of nodes are attacked.  ...  comparable throughput and latency as existing permissioned blockchains' protocols  ...  EGES achieved reasonable efficiency and DoS resiliency in a geo-replicated setting.  ...
