In this case, the hyperboxes represent individual training data points and the outputs of the hyperbox layer nodes can be treated as the classification values.

However, as it has also been indicated in the literature, removing all the misclassified samples can sometimes result in dropping whole regions of a class and essentially overediting the training set. In terms of the GFMM classifier generated for such edited data set, due to overediting, the classification models have turned out to be too simple to accurately capture the decision boundaries. Therefore, the third data editing procedure has been designed using an observation that some input data samples are more consistently used for generation of classifiers during the cross-validation process than others. It also applies to the misclassified samples, whereas some of the samples will be misclassified consistently while others only occasionally. The approach based on the rejection of all the samples which have been misclassified at least ones during the multiple cross-validation does not attempt to take this fact into\n", "account in any way. In order to rectify this problem, an approach which will estimate the probability of every single point in the original training data set to be kept during the multiple cross-validation.
