Cross-Validation Without Doing Cross-Validation in Genome-Enabled Prediction

open access: yesG3: Genes, Genomes, Genetics, 2016
Cross-validation of methods is an essential component of genome-enabled prediction of complex traits. We develop formulae for computing the predictions that would be obtained when one or several cases are removed in the training process, to become ...

Cross-Validation Visualized: A Narrative Guide to Advanced Methods

open access: yesMachine Learning and Knowledge Extraction
This study delves into the multifaceted nature of cross-validation (CV) techniques in machine learning model evaluation and selection, underscoring the challenge of choosing the most appropriate method due to the plethora of available variants.

Targeted cross-validation

open access: yesBernoulli, 2023
In many applications, we have access to the complete dataset but are only interested in the prediction of a particular region of predictor variables. A standard approach is to find the globally best modeling method from a set of candidate methods. However, it is perhaps rare in reality that one candidate method is uniformly better than the others.

Missing value imputation using least squares techniques in contaminated matrices

open access: yesMethodsX, 2022
This paper describes strategies to reduce the possible effect of outliers on the quality of imputations produced by a method that uses a mixture of two least squares techniques: regression and lower rank approximation of a matrix.

Modify Leave-One-Out Cross Validation by Moving Validation Samples around Random Normal Distributions: Move-One-Away Cross Validation

open access: yesApplied Sciences, 2020
The leave-one-out cross validation (LOO-CV), which is a model-independent evaluate method, cannot always select the best of several models when the sample size is small.

The Problem of Measurement Equivalence or Invariance in Instruments

open access: yesInternational Journal of Assessment Tools in Education, 2021
The purpose of this study is to discuss the validity of equivalence in the sample groups of young and adult; females and males in the scale of assessing the attitudes towards foreign language skills and to offer the researchers that will use this scale ...

Comprehensive validation of silicon cross sections

open access: yesNuclear Engineering and Technology, 2020
Silicon, especially silicon in the form of SiO2, is a major component of rocks. Final spent fuel storages, which are being designed, are located in suitable rock formations in the Earth's crust.

Balanced Leave-One-Subject-Out Cross- Validation for Microsleep Classification

open access: yesCurrent Directions in Biomedical Engineering, 2021
Inter-individual differences in the feature distribution of electroencephalograms (EEG) during microsleep (MS) raise questions about the generalizability of the methodology, because methodology should have the same validity for subjects to be included in

Spatial Regression Models for Field Trials: A Comparative Study and New Ideas

open access: yesFrontiers in Plant Science, 2022
Naturally occurring variability within a study region harbors valuable information on relationships between biological variables. Yet, spatial patterns within these study areas, e.g., in field trials, violate the assumption of independence of ...
