Sequential Learning in Wireless Communications and Computer Networks

Advisor: Prof. Jianping Pan

In this research project, we model the problems in wireless communications and computer networks (e.g., wireless caching systems, opportunistic spectrum access, opportunitic routing, and task dispatching in crowdsourcing, etc) as the multi-armed bandit problems. Theoretically, driven by problems, we develop new variants of bandits and derive regret bounds. Practically, we build systems implementing the proposed algorithms to solve the identified problems.

Machine Learning Meets Radio Channel Modeling

Advisors: Prof. Ruonan Zhang, Prof. Jianping Pan

Many problems in radio channel modeling can be solved by machine learning techniques. In this project, we focus on the clustering of Multi-Path Components (MPCs) in radio channel modeling. Extensive field channel measurements have shown that MPCs are not independent to each other but distributed in groups. However, many automatic clustering tools does not consider the effect of noise. We are motivated to develop effective algrotihms to cluster those MPCs automatically while reducing the effect of noise.
