Nested Distributed Gradient Methods with Stochastic Computation Errors
Charikleia Iakovidou, Ermin Wei
In this work, we consider the problem of a network of agents collectively minimizing a sum of convex functions. The agents in our setting can only access their local objective func…

Nested Distributed Gradient Methods with Adaptive Quantized Communication
Albert S. Berahas, Charikleia Iakovidou, Ermin Wei
In this paper, we consider minimizing a sum of local convex objective functions in a distributed setting, where communication can be costly. We propose and analyze a class of neste…
