w88 casino News Network (provided by the w88 casino of Statistics)On March 26, at the invitation of the w88 casino of Statistics, Professor Qi Yongcheng from the Department of Mathematics and Statistics of the University of Minnesota, Duluth, USA, gave a wonderful academic report titled "Maximum Values of Sparse Isocorrelated Gaussian Fields and Their Applications" to teachers and students of the w88 casino of Statistics.

Before the lecture started, the host Professor Xiong Wei gave a brief introductionProfessor Qi Yongcheng’s learning experience and academic achievements. He has been deeply engaged in the field of probability statistics for a long time, and has made fruitful achievements in the fields of limit theory, empirical likelihood, high-dimensional statistics and random matrices, and has published more than 100 academic papers.

In the report, Qi Yongcheng explained the extreme value problem of sparse and other related Gaussian fields, systematically introduced the relevant theories and their important role in high-dimensional statistics, and combined with specific research results, explained the core ideas in a simple and profound way. At the same time, he also demonstrated the application value of this theory in solving several open problems in the relevant literature. During the interactive session, teachers and students on site actively asked questions, and Qi Yongcheng answered them in detail one by one, and encouraged students to actively explore the application of limit theory in high-dimensional statistics. Finally, Professor Xiong Wei summarized the report and expressed his thanks again.

The cutting-edge content and vivid explanations of this lecture not only deepened teachers and students’ understanding of related research directions, but also provided new ideas for cross-research on high-dimensional statistics and extreme value theory.(Written by: Xiong Wei, Ma Shaopei, Photographed by: Wang Xuan, Reviewed by: Li Yue, Guo Wei)
