受我院刘应状教授的邀请,麻省理工学院Lizhong Zheng(郑立中)教授将于本月中旬访问我校。郑教授是无线通信与信息论领域的领军人物,其博士期间的两篇突破性论文——非相干MIMO信道的容量刻画以及分集-复用增益折衷的理论框架——即已奠定令人瞩目的学术地位;其工作以关注学科根本性问题,研究结果深刻、简洁且优雅著称。
1月12日上午9:30,在武汉光电国家实验室A101室,郑教授将进行一场关于将信息论应用于统计推断的学术报告。除了技术部分,报告还将重点涉及研究方法论的讨论,特别地,将涉及如何从EE的视角进行Big Data(大数据)相关问题的研究,以及EE与CS在研究Big Data问题上的风格差异。
本报告无须信息论的相关背景,欢迎感兴趣的师生(包括本科生)参加。
Statistical Inference via Information Geometry
--An Example of “EE Style” Research in the Big Data Era
Speaker: Prof.Lizhong Zheng, MIT
Time:9:30 AM, Jan. 12, 2015
Location: Rm. A101,Wuhan National Lab. for Optoelecronics.
Abstract:
This talkhas a technical part and a non-technical part.
Thetechnical part is an overview of our new results on applying informationgeometry on statistical inference problems. We explain some limitations of theconventional information theoretic analysis, and present a method to go beyondsuch limits. This involves a new formulation of the inference problems, a newset of information metrics, and new operational meanings of these metrics inthe context of data processing. We argue that our approach is a fundamentalextension of the conventional approaches, and a key to put a systematicframework to the new machine learning type of problems.
I thenon-technical part of this talk, we try to report some new trends in thedevelopment of the theory for information technology, and the differencebetween an EE-style and a CS-style research. This reflects our personal tastesin picking research problems and in driving the direction of fundamentalresearch, with the hope of motivating more students in pursuing researchresults from a diverse range of directions.
