Deflated preconditioned conjugate gradient method for solving single-step BLUP models efficiently [PDF]

open access: goldGenetics Selection Evolution, 2018
Background The single-step single nucleotide polymorphism best linear unbiased prediction (ssSNPBLUP) method, such as single-step genomic BLUP (ssGBLUP), simultaneously analyses phenotypic, pedigree, and genomic information of genotyped and non-genotyped

On the preconditioning of the primal form of TFOV-based image deblurring model [PDF]

open access: yesScientific Reports, 2023
To address the staircasing problem in deblurred images generated by a simple total variation (TV) based model, one approach is to use the total fractional-order variation (TFOV) image deblurring model.

GPU-Based N-1 Static Security Analysis Algorithm With Preconditioned Conjugate Gradient Method [PDF]

open access: goldIEEE Access, 2020
N-1 static security analysis (SSA) is an important method for power system stability analysis that requires solving N alternating-current power flows (ACPF) for a system with N elements to obtain strictly accurate results.

Least squares reverse time migration imaging with illumination preconditioned based on improved PRP conjugate gradients [PDF]

open access: yesScientific Reports, 2023
Least squares reverse time migration (LSRTM) imaging is the one of the most accurate methods for migration imaging at present, and Polak–Ribiere–Polyak conjugate gradient (PRPCG) for LSRTM has the good numerical performance but weak convergence, so we ...

Computational strategies for the preconditioned conjugate gradient method applied to ssSNPBLUP, with an application to a multivariate maternal model [PDF]

open access: yesGenetics Selection Evolution, 2020
Background The single-step single nucleotide polymorphism best linear unbiased prediction (ssSNPBLUP) is one of the single-step evaluations that enable a simultaneous analysis of phenotypic and pedigree information of genotyped and non-genotyped animals ...

Preconditioning the modified conjugate gradient method

open access: hybridGlobal Journal of Mathematical Sciences, 2010
In this paper, the convergence analysis of the conventional conjugate Gradient method was reviewed. And the convergence analysis of the modified conjugate Gradient method was analysed with our extension on preconditioning the algorithm. Convergence of the algorithm is a function of the condition number of M-1A.

An efficient genomic prediction method without the direct inverse of the genomic relationship matrix [PDF]

open access: yesFrontiers in Plant Science, 2022
GBLUP, the most widely used genomic prediction (GP) method, consumes large and increasing amounts of computational resources as the training population size increases due to the inverse of the genomic relationship matrix (GRM).
