During training, a correct classification of 99.1% was achieved for the neural network while the validationset achieved 86.8% correct classification. Starting from different random initial weights, ten networks were trained until the cross-entropy on the validationset reached a minimum for each of them. This would suggest then that for very small corpora, several learned models might be developed and a separate tagged validationset used to choose among the models. As learning progresses in a noisy data set, the closest approximation to the function generally occurs before overfitting, at which point the error u of an independent validationset increases. The error on the validationset is used as a proxy for the generalization error in determining when overfitting has begun.

However one must be careful to preserve the total blinding of the validationset from the training procedure, otherwise bias may result.

For example, for binary classification problems, each case in the validationset is either predicted correctly or incorrectly.

Cross-validation is a way to predict the fit of a model to a hypothetical validationset when an explicit validationset is not available.

If carried out properly, and if the validationset and training set are from the same population, cross-validation is nearly unbiased.

A grid search algorithm must be guided by some performance metric, typically measured by cross-validation on the training set or evaluation on a held-out validationset.

Averaging the quality of the predictions across the validation sets yields an overall measure of prediction accuracy.
