摘要
本文结合残量Bregman迭代方法以及不动点迭代方法提出一种新迭代方法,将其应用于信号恢复问题.数值试验表明,新方法避免了Bregman迭代方法产生的停滞现象且较线性Bregman迭代方法更稳定、快速、有效.
In this paper,based on the residual Bregman iterative algorithm and fixed point iteration,we propose a novel Bregman iterative algorithm. The novel algorithm is then applied to signal recovery. Numerical tests indicate the novel algorithm can avoid the stagnation and is more rapid,stable and efficient than the linearized Bregman algorithm.
