An Explicit Quasi-Newton Update for Sparse Optimization Calculations
A new quasi-Newton updating formula for sparse optimization calculations is presented. It makes combined use of a simple strategy for fixing symmetry and a Schubert correction to the upper triangle of a permuted Hessian approximation. Interesting properties of this new update are that it is closed form and that it does not satisfy the secant condition at every iteration of the calculations. Som...
متن کاملA new quasi-Newton pattern search method based on symmetric rank-one update for unconstrained optimization
This paper proposes a new robust and quickly convergent pattern search method based on an implementation of OCSSR1 (Optimal Conditioning Based Self-Scaling Symmetric Rank-One) algorithm [M.R. Osborne, L.P. Sun, A new approach to symmetric rank-one updating, IMA Journal of Numerical Analysis 19 (1999) 497–507] for unconstrained optimization. This method utilizes the factorization of approximatin...
متن کاملA New IRIS Segmentation Method Based on Sparse Representation
Iris recognition is one of the most reliable methods for identification. In general, itconsists of image acquisition, iris segmentation, feature extraction and matching. Among them, iris segmentation has an important role on the performance of any iris recognition system. Eyes nonlinear movement, occlusion, and specular reflection are main challenges for any iris segmentation method. In thi...

متن کاملQuasi - Newton Trust - Region Method
The classical trust-region method for unconstrained minimization can be augmented with a line search that finds a point that satisfies the Wolfe conditions. One can use this new method to define an algorithm that simultaneously satisfies the quasi-Newton condition at each iteration and maintains a positive-definite approximation to the Hessian of the objective function. This new algorithm has s...
