Randomized Reactive Redundancy for Byzantine Fault-Tolerance in Parallelized Learning
Nirupam Gupta, Nitin H. Vaidya
This report considers the problem of Byzantine fault-tolerance in synchronous parallelized learning that is founded on the parallelized stochastic gradient descent (parallelized-SG…
Exact Byzantine Consensus on Arbitrary Directed Graphs under Local Broadcast Model
Muhammad Samir Khan, Lewis Tseng, Nitin H. Vaidya
We consider Byzantine consensus in a synchronous system where nodes are connected by a network modeled as a directed graph, i.e., communication links between neighboring nodes are…
Asynchronous Byzantine Consensus on Undirected Graphs under Local Broadcast Model
Muhammad Samir Khan, Nitin Vaidya
In this work we look at Byzantine consensus in asynchronous systems under the local broadcast model. In the local broadcast model, a message sent by any node is received identicall…
Exact Byzantine Consensus on Undirected Graphs under Local Broadcast Model
Muhammad Samir Khan, Syed Shalan Naqvi, Nitin H. Vaidya
This paper considers the Byzantine consensus problem for nodes with binary inputs. The nodes are interconnected by a network represented as an undirected graph, and the system is a…
Byzantine Consensus under Local Broadcast Model: Tight Sufficient Condition
Muhammad Samir Khan, Nitin H. Vaidya
In this work we consider Byzantine Consensus on undirected communication graphs under the local broadcast model. In the classical point-to-point communication model the messages ex…
Distributed Learning with Adversarial Agents Under Relaxed Network Condition
Pooja Vyavahare, Lili Su, Nitin H. Vaidya
This work studies the problem of non-Bayesian learning over multi-agent network when there are some adversarial (faulty) agents in the network. At each time step, each non-faulty a…
