A survey of cross-validation procedures for model selection [PDF]

open access: yes, 2009
Used to estimate the risk of an estimator or to perform model selection, cross-validation is a widespread strategy because of its simplicity and its apparent universality.

PENAKSIRAN FUNGSI DENSITAS TIPE KERNEL DENGAN METODE CROSS-VALIDATION (C-V)

open access: yesBarekeng, 2007
The choice of the bandwidth h is the main problem of kernel density function. In some situations it might be quite useful to have a set of retes corresponding to different bandwidth.It is necessary to agree which bandwidth is an appropriate one.

A theory of cross-validation error [PDF]

open access: yes, 1994
This paper presents a theory of error in cross-validation testing of algorithms for predicting real-valued attributes. The theory justifies the claim that predicting real-valued attributes requires balancing the conflicting demands of simplicity and ...

On Estimating Model in Feature Selection With Cross-Validation

open access: yesIEEE Access, 2019
Both wrapper and hybrid methods in feature selection need the intervention of learning algorithm to train parameters. The preset parameters and dataset are used to construct several sub-optimal models, from which the final model is selected. The question

Measuring the bias of incorrect application of feature selection when using cross-validation in radiomics

open access: yesInsights into Imaging, 2021
Background Many studies in radiomics are using feature selection methods to identify the most predictive features. At the same time, they employ cross-validation to estimate the performance of the developed models.
