Analysis of weight initialization routines for conjugate gradient ...

If we choose the conjugate vectors carefully, then we may not need all of them to obtain a good approximation to the solution . So, we want to regard the conjugate gradient method as an iterative method. This also allows us to approximately solve systems where n is so large that the direct method would take too much time. We denote the initial guess for x∗ by x0 (we can assume without loss of generality that x0 = 0, o… WebAnother version of the conjugate gradient algorithm was proposed by Polak and Ribiére. As with the Fletcher-Reeves algorithm, traincgf, the search direction at each iteration is determined by. p k = − g k + β k p k − 1. For the Polak-Ribiére update, the constant β k is computed by. β k = Δ g k − 1 T g k g k − 1 T g k − 1.
