# Model Object (IModel Interface)

This object represents a trained model which can be used for classifying documents.

## Properties

| Name           | Type                                                                                                                                                                                                                                         | Description                                                                                                                                                                                                                                                           |

The type depends on the document features that the classifier considers when assigning a category.                                                                                                                         |
