How it works...

To start, you need to have an iterator to traverse and prepare the data. In step 1, we used the record reader data to create the dataset iterator. The purpose of the iterator is to have more control over the data and how it is presented to the neural network.

Once the appropriate normalization method has been identified (NormalizerStandardize, in step 2), we use fit() to apply the normalization to the dataset. NormalizerStandardize normalizes the data in such a way that feature values will have a zero mean and standard deviation of 1.
