# FeatureFields

A list of field names for the fields in training and classification documents that you want to use to classify the document. Separate multiple field names with commas. There must be no space before or after a comma.

Feature fields generally consist of short pieces of information, which the classifier uses as features for a class. When you train a class, the classifier analyzes the content of the specified feature fields in your training documents to create the class definition. For example, if you create a food classifier, you might use an field that contains ingredients.

Ideally, the feature fields contain small pieces of information, such as name, or very brief description. A good choice of feature field is similar to a good choice of `ParametricType` field. HPE recommends that you do not use fields that contain large sections of text.
