Practical use of robust GCV and modified GCV for spline smoothing [PDF]
Computational Statistics, 2015 Generalized cross-validation (GCV) is a popular parameter selection criterion for spline smoothing of noisy data, but it sometimes yields a severely undersmoothed estimate, especially if the sample size is small.

GCV for Tikhonov regularization by partial SVD
BIT Numerical Mathematics, 2017 Tikhonov regularization is commonly used for the solution of linear discrete ill-posed problems with error-contaminated data. A regularization parameter that determines the quality of the computed solution has to be chosen.

Input Layer Regularization and Automated Regularization Hyperparameter Tuning for Myelin Water Estimation Using Deep Learning. [PDF]
NMR BiomedWe propose a novel deep learning algorithm for predicting the myelin water fraction from multiple gradient‐echo or spin‐echo pulse sequences arising in magnetic resonance relaxometry (MRR) measurements of the human brain. Our method incorporates both regularized nonlinear least squares and pure deep learning through a concatenation paradigm known as ...

Efficacy of Fixed Low-Power Long-Duration Radiofrequency Ablation of Ventricular Arrhythmias Originating From the Left Ventricular Summit. [PDF]
J ArrhythmEfficacy and safety of a fixed low‐power, long‐duration radiofrequency catheter ablation of ventricular arrhythmias originating from the left ventricular summit. ABSTRACT Background Radiofrequency catheter ablation (RFCA) of ventricular arrhythmias originating from the left ventricular summit (LVS‐VAs) remains challenging.

Robust GCV choice of the regularization parameter for correlated data
Journal of Integral Equations and Applications, 2010 We consider Tikhonov regularization of linear inverse problems with discrete noisy data containing correlated errors. Generalized cross-validation (GCV) is a prominent parameter choice method, but it is known to perform poorly if the sample size n is ...

Performance of Robust GCV and Modified GCV for Spline Smoothing [PDF]
Scandinavian Journal of Statistics, 2011 Abstract. While it is a popular selection criterion for spline smoothing, generalized cross‐validation (GCV) occasionally yields severely undersmoothed estimates. Two extensions of GCV called robust GCV (RGCV) and modified GCV have been proposed as more stable criteria. Each involves a parameter that must be chosen, but the only guidance has come from

Genetic studies on diversity and variability in dolichos bean (Lablab purpureus L.)
Electronic Journal of Plant Breeding, 2021 The field experiment was carried out by using twenty-six field bean genotypes to study the genetic divergence and genetic variability parameters. The characters studied were days to 50 per cent flowering, days to maturity, plant height, the number of
