2016年5月19日上午，伊利诺伊大学芝加哥分校(University of Illinois at Chicago)电子与计算机工程系（Electrical and Computer Engineering）主任Rashid Ansari教授应自动化学院刘德荣教授的邀请，在机电信息楼518会议室，做了题为“New Approaches to Energy-efficient Data Aggregation Wireless Sensor Networks”的学术报告。自动化学院部分老师和研究生参加了学术报告。
报告会开始，董冀媛老师代表学院师生欢迎Rashid Ansari教授并向其介绍了北京科技大学以及自动化学院。随后Rashid Ansari教授也就学校学院的概况向我院师生进行了介绍，包括伊利诺伊大学芝加哥分校以及电子与计算机工程学院的概况，并着重介绍了北京科技大学于伊利诺伊大学芝加哥分校的3+2项目。
在Rashid Ansari教授学术报告中，他重点介绍了其团队的研究，讲解了ST-HDACS并用仿真结果证明了其有效性。这次学术报告主要讨论了如何利用压缩传感（Compressive Sensing）实现数据集成过程中更好的计算与交流。压缩传感主要是用于减小传输数据规模，在能效与其他性能指标方面，体现了其巨大的优越性。在非光滑多模态数据集成领域，一般使用自适应方法；在时空数据领域，Rashid Ansari教授提出了一种新的方法——时空层次数据聚集压缩传感（Spatio-Temporal Hierarchical Data Aggregation Compressive Sensing）。
会后，Rashid Ansari教授欢迎同学们到伊利诺伊大学芝加哥分校学习交流。作为自动化学院的学生，对数据处理并不陌生，但是Rashid Ansari教授的学术报告着实让大家开了眼界。同学们若有留学意向的，抓紧行动吧！
报告人简介:
Rashid Ansari received the Ph.D. degree in electrical engineering and computer science from Princeton University, Princeton, NJ, in 1981. He is currently Professor and Head in the Department of Electrical and Computer Engineering at the University of Illinois at Chicago (UIC).
