Fast Optimization with Zeroth-Order Feedback in Distributed, Multi-User MIMO Systems

Olivier Bilenne, Panayotis Mertikopoulos, E. Veronica Belmega

In this paper, we develop a gradient-free optimization methodology for efficient resource allocation in Gaussian MIMO multiple access channels. Our approach combines two main ingre…

Distributed stochastic optimization via matrix exponential learning

Panayotis Mertikopoulos, E. Veronica Belmega, Romain Negrel +1

In this paper, we investigate a distributed learning scheme for a broad class of stochastic optimization problems and games that arise in signal processing and wireless communicati…
