题目: Rate-optimal Perturbation Bounds for Singular Spaces, SVD and PCA报告人：张安如 （威斯康星大学-麦迪逊分校）时间： 2019年12月26号 16:30-17:30地点：北航沙河主楼E405摘要: Perturbation bounds for singular spaces, principal component analysis (PCA) and singular value decomposition (SVD) are fundamental tools and have been widely used in statistics, machine learning, and applied mathematic...
题目: Testing and estimation for clustered signals报告人: Prof. Hongyuan Cao (Florida State University)时间: 2019.12.26 14:00-15:00地点: 沙河主楼（二期）E404摘要: We propose a change-point detection method for large scale multiple testing problems with data having clustered signals. Unlike the classic change-point setup, the signals can vary in size within a cluster. The clustering struct...

报告题目：From optimal Transportation to Nonlinear Optimisation报告人：刘佳堃 教授(University of Wollongong，澳大利亚)报告时间：2019.12.13 13:00-14:00报告地点：沙河主楼E405摘要：In this talk, we first introduce the optimal transportation problem and its Kantorovich’s dual functional, from which arises the research area of linear programming, also called linear optimisation. As an exten...
