RISStable estimation of a covariance matrix guided by nuclear norm penalties
Determination of likelihood ratios for forensic voice comparison using principal component analysis
Hypercube estimators: Penalized least squares, submodel selection, and numerical stability
Two optimal Dai–Liao conjugate gradient methods
. and the other one is obtained by minimizing Frobenius
condition number of the search direction matrix. Global convergence analyses are made briefly. Numerical results are reported; they demonstrate effectiveness of the suggested adaptive choices....
An Adaptive Hager-Zhang Conjugate Gradient Method
Based on a singular value study, lower and upper bounds for the condition number of the
matrix which generates search directions of the Hager-Zhang conjugate gradient method are obtained.
Then, based on the insight gained by our...
An iterative method for damage identification of skeletal structures utilizing biconjugate gradient method and reduction of search space
matrix significantly reduces the condition number of the system. Moreover, based on the characteristics of the damage vector, a new direct search algorithm is employed to increase the efficiency of the suggested damage detection scheme by reducing...
An enhanced iterative method for inverse structural problems
method with the pre-conditioners known as AINV and CIMGS are the proper combinations for the solution technique. It is also shown that a definite norm known as \\\\\\"condition number\\\\\\" is a good criterion for the evaluation of the solution accuracy....
