摘要:
针对压缩感知模型,讨论了基于l0正则化的正交匹配追踪算法(OMP)与基于l1正则化的同伦算法(HM)和迭代加权最小二乘法(IRLS).通过数值实验结果分析,验证了3种算法的有效性,且相对于2种基于l1正则化的算法,OMP算法的迭代次数与耗时更少,均方误差更小.
Abstract:
For compressive sensing,orthogonal matching pursuit algorithm(OMP)based on l0 norm regularization,homotopy algorithm(HM)based on l1 norm regularization and iteratively reweighted least squares algorithm(IRLS)based on l1 norm regularization are introduced.In numerical experiment,the validity of three algorithms above through analysis of numerical result are proved.Furthermore,for lower CPU cost and smaller mean square error,OMP is more efficient than other two algorithms based on l1 norm regularization.
