讲座人 Dr. Gan Zheng
讲座人介绍 Dr. Gan Zheng received the PhD degree in Electrical and Electronic Engineering from The University of Hong Kong in 2008. He is currently a Senior Lecturer in the Wolfson School of Mechanical, Electrical and Manufacturing Engineering, Loughborough University, UK.
His research interests focus on 5G and beyond wireless networks, with current emphasis on wireless proactive caching, full-duplex radio, and machine learning for wireless communications. He has published over 100 papers in international journals and conferences, which have received more than 3600 citations. He received five international best paper awards, including the prestigious 2015 GLOBECOM Best Paper Award and the first recipient of the 2013 IEEE Signal Processing Letters Best Paper Award. He serves as an Associate Editor for IEEE Communications Letters.
讲座内容 Caching popular contents at small cells has been proposed as a promising solution to reduce the backhaul demand and transmission delays, and thus alleviate many bottleneck problems in wireless content networks.  However, content popularity keeps changing over spatio-temporal domains. This calls for effective caching placement schemes that can adapt quickly to the dynamic content popularity. In this talk, we will discuss the joint optimization of content placement and BS densities to minimize the content missing probability in a multi-cluster heterogeneous network. We introduce the convex optimization method for the long-term offline cache placement, and the deep learning based approach for frequent online cache update. The numerical results demonstrate that the proposed algorithms can keep track of the variation of content popularity and maintain low missing probability.
