A Brief Introduction to Sparse Optimization: Algorithm Development

Zhao Yunbin, Shenzhen big data research institute

 

Abstract: seeking sparsity comes from a common request in variety of scientific and engineering fields. The sparse optimization is fundamentally essential to the modern theory, algorithms and applications of compressive sensing, signal and image processing, statistical learning and so on. This talk will give a brief introduction to sparse optimization, focusing on the algorithm development in data reconstruction/recovery/approximation. Four types of mainstream algorithmic frameworks will be discussed: L1-minimization, nonlinear optimization, hard thresholding and orthogonal matching pursuit as well as their important variants.  

 

Reporter: Zhao Yunbin was appointed senior research scientist of Shenzhen big data research institute in March 2020. In 1998, he received a doctorate in operations research and cybernetics from the Academy of mathematics and Systems Sciences, Chinese Academy of Sciences; From 1999 to 2002, he was a postdoctoral researcher in Computational Mathematics and scientific engineering computing of the Chinese Academy of Sciences, the Chinese University of Hong Kong and Fields Institute of mathematics of Canada; Worked in the Academy of mathematics and Systems Sciences, Chinese Academy of Sciences from 2001 to 2010; From 2007 to 2020, he taught at the school of mathematics, University of Birmingham, UK. He has been engaged in Applied Mathematics, operations research, computational optimization, signal processing and compressed sensing for a long time. In the field of sparse signal processing and compressed sensing, a series of outstanding achievements have been achieved, such as RSP signal reconstruction theory, uniform stability theory of convex reconstruction algorithm, dual densification method, and optimal threshold high-performance algorithm. He has published 60 academic papers and an English monograph on sparse optimization. He has been a member of the editorial board of several international mathematical journals
