Adaptive extra-gradient methods for min-max optimization and games
Kimon Antonakopoulos, E. Veronica Belmega, Panayotis Mertikopoulos
We present a new family of min-max optimization algorithms that automatically exploit the geometry of the gradient data observed at earlier iterations to perform more informative e…
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…
Man-in-the-Middle and Denial of Service Attacks in Wireless Secret Key Generation
Miroslav Mitev, Arsenia Chorti, E. Veronica Belmega +1
Wireless secret key generation (W-SKG) from shared randomness (e.g., from the wireless channel fading realizations), is a well established scheme that can be used for session key a…
