WebThe function ˚() is referred to as the penalty function (or regularization function). If ˚(x) = jxj, then (4) is the same as (1). For sparse signal processing, ˚(x) should be chosen so as to promote sparsity of x. It is common to set ˚(x) = jxj, especially because it is a convex function unlike many other sparsity promoting penalty functions.
