Smoothing and Regularization with Modified Sparse Approximate Inverses
Sparse approximate inverses 𝑀 which satisfy min𝑀‖𝐴𝑀−𝐼‖𝐹 have shown to be an attractive alternative to classical smoothers like Jacobi or Gauss-Seidel (Tang and Wan; 2000). The static and dynamic computation of a SAI and a SPAI (Grote and Huckle; 1997), respectively, comes along with advantages lik...
