Web1 de abr. de 2024 · The gradient neural network (GNN) method is a novel approach to solving matrices. Based on this method, this paper improves the gradient neural network (IGNN) model with a better effect. The convergence speed is increased by replacing the X i − 1 ( k) matrix in the original gradient neural network with the current matrix X i − 1 ( k + 1).
