Abstract
By the application of a technique from the statistical pattern recognition literature, the editing algorithm [Devijver 1982], a learning set can be transformed to a data set in which overlap between classes is effectively removed. Because it can be proven that an edited data set is close to Bayes-optimal for the nearest-neighbour classifier, it is very likely that a multi-layer network which classifies all samples in the edited learning set correctly, is also close to Bayes-optimal. In this paper we investigate the performance of the backpropagation algorithm on edited data sets. This leads to an optimal criterion to stop the learning phase and to a moderate improvement in learning speed.
