Using the Machine Learning Classifier Trainer

Below are the steps that you need to follow for using the Machine Learning Classifier Trainer activity.

  1. Use the Taxonomy Manager Wizard to define your document types.
  2. Drag a Machine Learning Classifier Trainer in a Train Classifiers Scope activity.
  3. In the Machine Learning Classifier wizard that automatically opens, add the ML Skill information.
  4. Click the Get Capabilities button. The wizard closes after this operation.
  5. From the drop-down, select a Project that you created in AI Fabric beforehand.
  6. Once a Project is selected, the list of datasets for that project is retrieved from AI Fabric. Select a Dataset from the drop-down.
  7. Select the Configure Classifiers option of the Train Classifiers Scope. A wizard is displayed.
  1. The Machine Learning Classifier Trainer is now ready for configuration. Start selecting the document types you want to train, by clicking the checkboxes next to the appropriate document types.
  2. Select from the available drop-down list, the correct data you wish to map to each document type. The drop-down list contains all document types that the Machine Learning Classifier Trainer, using the ML Skill entered in the Machine Learning Classifier wizard, declares as classification capability.
  3. To check if you are using the latest capabilities of the classifier, you can click the Get or refresh classifier capabilities which opens the Machine Learning Classifier wizard.
  4. Selecting one of the options from a drop-down list automatically confirms that field.
  1. Select the Save button once all document types are configured properly.
