Normalizing data for network efficiency

Normalization makes a neural network's job much easier. It helps the neural network treat all the features the same, irrespective of their range of values. The main goal of normalization is to arrange the numeric values in a dataset on a common scale without actually disturbing the difference in the range of values. Not all datasets require a normalization strategy, but if they do have different numeric ranges, then it is a crucial step to perform normalization on the data. Normalization has a direct impact on the stability/accuracy of the model. ND4J has various preprocessors to handle normalization. In this recipe, we will normalize the data.
