Title:
Modified projection and contraction methods for solving the split feasibility problem
Time & Venue:

Abstract:

This talk, I first review the split feasibility problem and recall the projection and contraction methods. Then, based on the 'optimal' choice of the step size, we introduce the modified projection and contraction methods and present convergence theorems of the proposed methods under suitable conditions. Finally, I compare the modified projection and contraction methods and the original methods through a typical sparse signal recovery problem (LASSO problem).
