Faster Stochastic Optimization with Arbitrary Delays via Asynchronous Mini-Batching
Amit Attia, Ofir Gaash, Tomer Koren
We consider the problem of asynchronous stochastic optimization, where an optimization algorithm makes updates based on stale stochastic gradients of the objective that are subject…
