An efficient spectral minimization of the Dai-Yuan method with application to image reconstruction

In this paper, a spectral Dai and Yuan conjugate gradient (CG) method is proposed based on the generalized conjugacy condition for large-scale unconstrained optimization, in which the spectral parameter is motivated by some interesting theoretical features of quadratic convergence associated with th...
