Basic pursuit denoising research based on the modified quasi-Newton method

DAI Shao-sheng,XIAO Han(Chongqing Key Laboratory of Signal and Information Processing,Chongqing University of Posts and Telecommunications,Chongqing 400065,P.R.China)  
To improve the efficiency of using basic pursuit algorithm which belongs to the sparse decomposition for one-dimensional signal de-noising,in this paper modified quasi-Newton method was proposed to solve the unconstrained optimization problem in the process of basic pursuit de-noising.On the basis of traditional quasi-Newton method,in this algorithm the Broyden-Fletcher-Goldfarb-Shanno(BFGS)-type formula was modified,the number of iterations was reduced effectively in the optimization process.Experimental results show that the modified quasi-Newton method compared to the traditional one can obviously improve the convergence rate of the objective function.
