During training, a correct classification of 99.1% was achieved for the neural network while thevalidationsetachieved 86.8% correct classification.
From theCambridge English Corpus
Starting from different random initial weights, ten networks were trained until the cross-entropy on thevalidationsetreached a minimum for each of them.
From theCambridge English Corpus
This would suggest then that for very small corpora, several learned models might be developed and a separate taggedvalidationsetused to choose among the models.
From theCambridge English Corpus
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 independentvalidationsetincreases.
From theCambridge English Corpus
The error on thevalidationsetis used as a proxy for the generalization error in determining when overfitting has begun.
From
Wikipedia
However one must be careful to preserve the total blinding of thevalidationsetfrom the training procedure, otherwise bias may result.
From
Wikipedia

From
Wikipedia

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

From theCambridge English Corpus
This can introduce systematic differences between the training and validation sets.
From
Wikipedia
Averaging the quality of the predictions across the validation sets yields an overall measure of prediction accuracy.
