Abstract
- In this paper, we investigate a more general sparse signal recovery minimization model and a smoothing neural network optimal method for compress sensing problem, where the objective function is a L p − q minimization model which includes nonsmooth, nonconvex, and non-Lipschitz quasi-norm L p norms 1 ≥ p > 0 and nonsmooth L q norms 2 ≥ p > 1 , and its feasible set is a closed convex subset of R n . Firstly, under the restricted isometry property (RIP) condition, the uniqueness of solution for the minimization model with a given sparsity s is obtained through the theoretical analysis. With a mild condition, we get that the larger of the q , the more effective of the sparse recovery model under sensing matrix satisfies RIP conditions at fixed p . Secondly, using a smoothing approximate method, we propose the smoothing inertial projection neural network (SIPNN) algorithm for solving the proposed general model. Under certain conditions, the proposed algorithm can converge to a stationary point. Finally, convergence behavior and successful recover performance experiments and a comparison experiment confirm the effectiveness of the proposed SIPNN algorithm. [ABSTRACT FROM AUTHOR]
