Abstract: A method of training a neural network comprises executing a neural network training process up to some predefined level of accuracy. The training set is then divided into a set of correctly trained elements and a set of incorrectly trained elements. An auxiliary data set is created from the correctly trained elements and cloned data elements corresponding to the incorrectly trained element. This auxiliary data set is perfectly trained with respect to the trained model for the original data set. A hybrid data set is produced as an average between the original data set and the auxiliary data set. The average is a weighted average according to some weighting parameter. Neural network training then continues to maintain the 100% positive rate from the auxiliary system, iteratively reducing the weighting parameter until the hybrid data set corresponds exactly to the original data set.
