When the Preprocess Numbers parameter is selected, all numbers will be replaced by a special word __number__ . This will allow the models to learn about number mentions in general rather than about specific number mentions. 

This is particularly useful for excluding numbers from features (i.e.: using the Preprocess Numbers parameter in combination with the model's stopwords) in cases for which the information encoded in numbers is of little value for classification purposes.
