WebFixed-point continuation (FPC) is an approach, based on operator-splitting and continuation, for solving minimization problems with ℓ1 ℓ 1 -regularization: We investigate the application of this algorithm to compressed sensing signal recovery, in which f (x) = 1 2∥Ax −b∥2 M f ( x) = 1 2 ‖ A x − b ‖ M 2, A ∈ Rm×n A ∈ R m × n and m ≤ n m ≤ n. 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.
