Analysis of Variance of Cross-Validation Estimators of the Generalization Error

J. Mach. Learn. Res., 2005
This paper brings together methods from two different disciplines: statistics and machine learning. We address the problem of estimating the variance of cross-validation (CV) estimators of the generalization error. In particular, we approach the problem of variance estimation of the CV estimators of generalization error as a problem in approximating ...

The L-Curve Criterion as a Model Selection Tool in PLS Regression

Journal of Probability and Statistics, 2019
Partial least squares (PLS) regression is an alternative to the ordinary least squares (OLS) regression, used in the presence of multicollinearity. As with any other modelling method, PLS regression requires a reliable model selection tool.

GRAV3D Validation using Generalized Cross-Validation (GCV) Algorithm by Lower Bounds Approach for 3D Gravity Data Inversion

Scientific Journal of Informatics, 2018
The completion of gravitational data inversion results in a smooth recovered model. GRAV3D is one software that can be used to solve 3D inversion problems of gravity data.

Correntropy–based density–preserving data sampling as an alternative to standard cross–validation [PDF]

, 2010
Estimation of the generalization ability of a predictive model is an important issue, as it indicates expected performance on previously unseen data and is also used for model selection.

Cross-validation of the general neuropsychological deficit scale (GNDS)

Archives of Clinical Neuropsychology, 1995
Sherer and Adams (1993) reported "limited support" for the validity of Reitan and Wolfson's (1988) Neuropsychological Deficit Scales. The present study was designed to cross-validate one of these scales--the General Neuropsychological Deficit Scale (GNDS).

An Impact Load History Reconstruction Method for Composite Structures Based on FBG Sensing Data and the GCV Principle

Sensors
Accurately and promptly acquiring the load history characteristics of impact events on composite aircraft structures is crucial for identifying impact-induced damage and developing high-fidelity digital twin models.

Validation of the Generalized Anxiety Disorder-7 in patients with COPD: a cross-sectional study

BMC Psychiatry, 2023
Background Patients with chronic obstructive pulmonary disease (COPD) often have comorbid generalized anxiety disorder (GAD), which requires early screening in respiratory clinics.

Evaluation of Fifteen Algorithms for the Resolution of the Electrocardiography Imaging Inverse Problem Using ex-vivo and in-silico Data

Frontiers in Physiology, 2018
The electrocardiographic imaging inverse problem is ill-posed. Regularization has to be applied to stabilize the problem and solve for a realistic solution. Here, we assess different regularization methods for solving the inverse problem.

Impact of Initial Treatment Setting on Survival in Relapsed Pediatric and AYA Bone Sarcomas: A Secondary Analysis of a Prospective Clinical Trial

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background Outcomes in relapsed or refractory pediatric and AYA bone sarcomas remain poor, and the impact of early referral to specialized sarcoma centers on survival is unclear. Early centralization of care may improve local and systemic treatment quality, but evidence in this population is limited.
