Distributed derivative-free learning method for stochastic optimization over a network with sparse activity

W Li, M Assaad, S Zheng - IEEE Transactions on Automatic …, 2021 - ieeexplore.ieee.org
This article addresses a distributed optimization problem in a communication network where
nodes are active sporadically. Each active node applies some learning method to control its …

Distributed zeroth-order stochastic optimization in time-varying networks

W Li, M Assaad - arXiv preprint arXiv:2105.12597, 2021 - arxiv.org
We consider a distributed convex optimization problem in a network which is time-varying
and not always strongly connected. The local cost function of each node is affected by some …
