Neural incomplete factorization: learning preconditioners for the conjugate gradient method

Paul Häusner, Ozan Öktem, Jens Sjölund

The convergence of the conjugate gradient method for solving large-scale and sparse linear equation systems depends on the spectral properties of the system matrix, which can be im…
