Recently, a new class of algorithms has been developed which iteratively build a sparse solution to an underdetermined linear system of equations. These algorithms are known in the literature as Iterative Shrinkage Algorithms (ISA). ISA algorithms depend on a thresholding parameter, which is usually provided by the user. In this paper we develop a new approach for automatically estimating this thresholding parameter. The proposed approach is general in a sense that it does not assume any… CONTINUE READING
