2.2. Descent conjugate gradient method For solving large-scale unconstrained minimization problems, the nonlinear conjugate gradient method is popular due to its simplicity, low storage, practical computation efficiency and nice convergence properties. The conjugate gradient method is to minimize a smooth ...
The performance gradient falls belowmin_grad. Validation performance (validation error) has increased more thanmax_failtimes since the last time it decreased (when using validation).
