Wireless Networks. I am interested in applications of machine learning and optimization to various aspects of wireless networks, from the physical layer to the application layer. Also, I am part of the Wireless Networking and Communications Group (WNCG). Please e-mail me for conference versions, if they are not available. [The abstract function does not yet work... but it will soon....]
