How to do it...

1. Create a dataset iterator from the data. Refer to the following demonstration for RecordReaderDataSetIterator:

DataSetIterator iterator = new RecordReaderDataSetIterator(recordReader,batchSize);

2. Apply the normalization to the dataset by calling the fit() method of the normalizer implementation. Refer to the following demonstration for the NormalizerStandardize preprocessor:

DataNormalization dataNormalization = new NormalizerStandardize();dataNormalization.fit(iterator);

3. Call setPreprocessor() to set the preprocessor for the dataset:

iterator.setPreProcessor(dataNormalization);
