Train Classifiers Scope

UiPath.IntelligentOCR.Activities.Training.TrainClassifiers

Provides a scope for any classifier activities you want to train. The activities must be manually dragged and dropped into the body of the activity.

Properties

Common
  • DisplayName - The display name of the activity.
Input
  • DocumentObjectModel - The Document Object Model you want to use to validate the document against. This model is stored in a Document variable and can be retrieved from the Digitize Document activity. Please see the documentation of each activity for more information on how to do this. This field supports only Document variables.
  • DocumentPath - The path to the document you want to validate. This field supports only strings and String variables.

    Note: The supported file types for this property field are .png, .gif, .jpe, .jpg, .jpeg, .tiff, .tif, .bmp, and .pdf.
  • DocumentText - The text of the document itself, stored in a String variable. This value can be retrieved from the Digitize Document activity. Please see the documentation of each activity for more information on how to do this. This field supports only strings and String variables.
  • HumanValidatedClassificationData - The output from the classification station, stored in an ClassificationResult[] proprietary variable. Incompatible with HumanValidatedData.
  • HumanValidatedData - The output from the validation station, stored in an ExtractionResult proprietary variable. Incompatible with HumanValidatedClassificationData.
    Note:
    • If the DocumentObjectModel and HumanValidatedData files are from different sources, an error is thrown at runtime.
    • The validation station can act as both classification and validation station.
  • Taxonomy - The Taxonomy against which the document is to be processed, stored in a DocumentTaxonomy variable. This field supports only DocumentTaxonomy variables.
Misc
  • Private - If selected, the values of variables and arguments are no longer logged at Verbose level.

The Configure Classifiers Wizard accessed via the Train Classifiers Scope allows you to choose which classifiers are trained for each document type.

Using the Configure Classifiers Wizard

Follow the steps below to configure the wizard:

  1. Add a Train Classifiers Scope activity to your workflow.
  2. Place a Classifier Trainer activity inside the Train Classifiers Scope activity.

    • Configure your classifiers by clicking on the Configure Classifiers button.
    • You can now see the Wizard.



  3. Select the checkboxes for the classifiers you want to activate for each document type. According to these checkboxes, classifiers execute only for the document types activated for each of them.



  4. Add any taxonomy mapping information into the text fields next to each checkbox (in case the classifier trainers use internal taxonomies that need to be mapped to the project taxonomy).
  5. Click the Get of refresh extractor capabilities button, for the classifiers that support this functionality, to easily map your taxonomy fields with the available document types, or refresh them in case the document types have changed.



  6. Click on the Save button once all the classifiers are selected.
