Optimal Complexity in Byzantine-Robust Distributed Stochastic Optimization with Data Heterogeneity
Qiankun Shi, Jie Peng, Kun Yuan +2
In this paper, we establish tight lower bounds for Byzantine-robust distributed first-order stochastic optimization methods in both strongly convex and non-convex stochastic optimi…
