The next seminar of the theme « Information processing - Random waves » will take place Friday June 28th, at 11:00 in the Pierre Cotton’s room.
Nguyen Linh Trung from Vietnam National University, Hanoi will give a talk on Modern subspace tracking for signal processing : A brief review and some developments


Abstract :
Subspace tracking aims to seek linear low-dimensional structure in a high-dimensional manifold in an adaptive setting. In this aspect, subspace tracking can be considered as a fast implementation of principal component analysis (PCA) for streaming data, which find many applications in signal processing, data analysis, telecommunication, biomedical imaging, and computer vision, etc.
In this talk, we would like to bring up some important aspects of modern subspace tracking for signal processing. First, we review some essential algorithms in the literature (up to 2010) where linear computational complexity of algorithms is the target. Then, we focus on modern subspace tracking which deals with many practical issues (e.g. outliers, missing data, higher-order data structure) and algorithmic issues (e.g. guaranteed convergence analysis). Finally, we will present some developments from our group on this topic, with illustrations in practical applications such as DOA tracking, radio-astronomy, video background-foreground separation, especially EEG signal analysis. Some recent trends and open perspectives are also discussed.

Biography :
Nguyen Linh Trung obtained his B.Eng. and Ph.D. degrees, both in Electrical Engineering, from Queensland University of Technology, Brisbane, Australia, in 1998 and 2005. Since 2006, he has been on the faculty of VNU University of Engineering and Technology (VNU-UET), a member university of Vietnam National University, Hanoi (VNU), where he is currently an associate professor of electronic engineering in the Faculty of Electronics and Telecommunications and director of the Advanced Institute of Engineering and Technology (AVITECH) of VNU-UET.
He is interested in signal processing methods, including time-frequency signal analysis, blind source separation, compressive sampling, tensor-based signal analysis, graph signal processing, and apply them to wireless communication and networking, biomedical engineering, with a current focus on large-scale processing.
He has held a postdoctoral research fellow position at the French National Space Agency (CNES), and visiting positions at Telecom ParisTech, Vanderbilt University, CentraleSupelec, the University Paris-Sud, the University Paris 13, the University of Illinois, the University of Technology Sydney.
He has served the Radio-Electronics Association of Vietnam (REV) and the IEEE on a number of positions, including member of REV Standing Committee, senior member of the IEEE, TPC co-chair of REV-IEEE annual International Conference on Advanced Technologies for Communications, managing editor of REV Journal on Electronics and Communications. He is currently the Technical Editor-in-Chief of the MIC Journal of Research and Development on Information and Communication Technology.
