Minimization of Transformed Penalty: Closed Form Representation and Iterative Thresholding Algorithms
Shuai Zhang, Jack Xin
The transformed penalty (TL1) functions are a one parameter family of bilinear transformations composed with the absolute value function. When acting on vectors, the TL1 pena…

Minimization of Transformed Penalty: Theory, Difference of Convex Function Algorithm, and Robust Application in Compressed Sensing
Shuai Zhang, Jack Xin
We study the minimization problem of a non-convex sparsity promoting penalty function, the transformed (TL1), and its application in compressed sensing (CS). The TL1 penalty…
