Signal Reconstruction Algorithm Based on l1-l0 Model

提出了一个弹性无约束l1-l0正则化模型,基于光滑化处理后的模型,给出求解该模型的迭代算法。证明了该算法产生的解序列有界,且分析了算法的全局收敛性。最后给出数值实验结果,表明算法的有效性。

An elastic unconstrained l1-l0 regularization model is proposed.Then,based on the smoothing model,the iterative algorithm for solving the model is given.Moreover,we proved that the iterative sequence generated by the algorithm is bounded,and the algorithm is convergent.Finally,the numerical experiment results demonstrate the effectiveness of the algorithm.
