Efficient Sparse Recovery With Arctangent Regularization: A Novel Iterative Thresholding Algorithm

Several existing works have revealed the effectiveness of arctangent-type penalties in exploiting sparsity for compressed sensing. However, addressing the subproblems associated with the arctangent penalty incurs considerable computational cost. Aiming to reduce complexity, we derive the closed-form...
