Abstract The nonlinear conjugate gradient method is a very useful technique for solving large scale minimization problems and has wide applications in many fields. In this paper, we present a new ...

Here we propose an alternative method based on conjugate gradients. The key, as we show, is that the EM step can be viewed (approximately at least) as a generalized gradient, making it natural to ...

Palm will produce the problem of scale inconsistent, rotation and translation during acquisition period,which may cause difficulties in identifying. To solve these problems, a novel palmprint ...
