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…
