**Machine Learning Classifier** uses a machine learning model deployed as an ML Skill in AI Center to perform document classification tasks.

## How to configure at design-time

Perform the following steps to use the **Machine Learning Classifier**:

1. Create a classifier model on AI Center.
   :::note
   Use the DocumentClassifier package that is available under Out-of-Box Document Understanding<sup>TM</sup> packages on AI Center. The data required for model training is collected through Machine Learning Classifier Trainer.
   :::
2. Use the **Taxonomy Manager Wizard** to define your document type, with the fields you are targeting for data extraction. The **Machine Learning Classifier** activity can work by default with the following:
   * 1040
   * 4506T
   * 990
   * Acord125
   * Acord126
   * Acord131
   * Acord140
   * Acord25
   * Bank Statements
   * Bills of Lading
   * Checks
   * Financial Statements
   * FM1003
   * I9
   * ID Cards
   * Invoices
   * Packing Lists
   * Passports
   * Purchase Orders
   * Receipts
   * Remittance Advices
   * Utility Bills
   * Vehicle Titles
   * W2
   * W9 forms.
3. Drag and drop the **Machine Learning Classifier** activity into the **Classify Document Scope** activity. Review the message and select **OK**.
4. In the **Machine Learning Classifier** wizard that automatically opens, provide the **ML Skill** and the **ApiKey** information.

## When to use

You should consider using the Machine Learning Classifier if:

* Your need to classify the single documents into different document types where no splitting is required.
* The custom document types are very similar. A trained Machine Learning Classifier can differentiate more easily between two similar document types than the Intelligent Keyword Classifier.
