Fixed point continuation
WebGeneralized projected gradient (GPG) algorithm for matrix completion [29] used a fixed-point iteration algorithm to solve proximal operators for a kind of non-convex surrogate functions. It also uses the continuation strategy to update the regularization parameter. As suggested in the paper, the initial value of λ in GPG is set ‖ Y ‖ ∞ ...
