Randomized iterative methods for linear systems: Generalization and acceleration
Speaker: Prof.Deren Han   Topic: Randomized iterative methods for linear systems: Generalization and acceleration   Time & Date: on April 03 (Monday) 10:00-11:00 (Beijing Time)   Venue:DY105   Abstract: We present a new framework for the analysis and design of randomized algorithms for solving various types of linear systems, including consistent or inconsistent, full rank or rank-defificient. Our method is formulated with four randomized sampling parameters, which allows the method to cover many existing randomization algorithms within a unified framework, including the doubly st…

Time Series and Nonparametric Regression
Abstract   Time series is a data type that commonly appears in applications from different areas. Existing methods developed for independent data, however, may not be directly applicable to time series data as ignoring the dependence can lead to distorted p-values and erroneous conclusions. In this talk, I will illustrate the use of nonparametric regression on time series data, which is robust to model misspecification issues when compared with popular parametric models. Implementation of nonparametric methods, however, can be computationally demanding especially in the current big data era.…

Frontier firms, inefficiency and productivity dynamics
Time & Date: 10:00 -11:00, ,Monday, January 11, 2021 Speaker: Dr. Shipei Zeng Join Zoom Meeting: https://cuhksz.zoom.com.cn/j/64582511292?pwd=TTBoUTBmcDlFeHRySk9LMnZhMy9vQT09 Meeting ID:645-8251-1292 Password: 123456   Abstract: Productivity dynamics occur when firms enter and exit a market. Contributions from firms to industry productivity can be decomposed into effects from entrants, exiters and incumbents. As opposed to productivity dynamics, productivity can also be decomposed into explanatory factors regarding efficiency and technical progress. These two patterns of decomposit…
