WebFeb 1, 2011 · In this paper, we study the convergence/recoverability properties of the fixed-point continuation algorithm and its variants for matrix rank minimization. Heuristics for determining the rank of the matrix when its true rank is not known are also proposed. Some of these algorithms are closely related to greedy algorithms in compressed sensing. 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 ‖ ∞ ...

WebThe fixed points of Equation ( 7) can be found by solving the system .
