The CGF is a network training function that updates weights and bias values according to the Fletcher–Reeves conjugate gradient algorithm. It has the smallest storage … 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. reddit subscription meal service
