2022年8月8日9:00，第四期信通与控制前沿技术系列讲座通过腾讯平台顺利召开。休斯敦大学Zhu Han教授受邀与通信工程学院师生开展题为“Distributionally Robust Optimization and Machine Learning for Communication Networks”线上学术交流活动。交流会由胡封晔教授主持。
讲座伊始，胡封晔教授对Zhu Han教授的学术背景、工作履历、研究方向以及获得的荣誉奖项等作出了详细的介绍。
随后，Han教授分享了本次讲座。他基于确定性概率分布和不确定概率分布两种方式入手，延伸介绍了三种常见的优化方式：随机规划鲁棒优化和分布式鲁棒优化。进而介绍了这三种优化方式具有的特征和相互的区别、联系，给出了它们分别适合应用的场景。总结了DRO方式的作用和应用的优势所在。在此基础上，Han老师分享了包括基于差异的 DRO 优化、使用风险规避和CVaR的DRO方法以及基于强化学习的DRO方法在内的三种DRO的案例分析。最后，他阐述了使用DRO方式的动机，并对DRO优化方式、CVaR、以及DRO RL方式的基本内核进行了概况。
会后，学院师生都积极提出问题、参与讨论，Han教授耐心的一一予以补充和解答。
本次讲座作为学院信通与控制前沿技术系列讲座的第四期，突破时间和空间的界限，为学院师生与国际一流高校专家学者提供开放交流的平台，为师生群体带来无线通信领域的前沿资讯和热点课题，也将进一步助推我院双一流学科建设工作。
