Creating a Classifier Model

Creating a Classifier Model

Use a data object as the source for the classifier model data.
A classifier model performs optimally when you use the input data to the Classifier transformation as the source for the model reference data.
  1. In Object Explorer, open or create a content set.
  2. Select the
    Content
    view.
  3. Select
    Classifier Models
    , and click
    Add
    .
    The Classifier Model wizard opens.
  4. Enter a name for the classifier model.
    Optionally, enter a text description of the model.
  5. Browse the Model repository and select the data object that contains the data to import.
    Do not select a social media data object.
    Click
    Next.
  6. Review the columns on the data object, and select one or more columns to add to the model. You can add reference data columns and a label column in the same operation.
    • To import a column of data as reference data, select the column name and click
      Data
      .
      You can select multiple data columns. The Developer tool merges the contents of the columns that you select to a single column.
    • To import a column of data as label values, select the column name and click
      Label
      .
    When you import reference data and label values, the Developer tool assigns the label on each row to the reference data string on the same row. You can preview the data before you select the columns. You can change the label assignments after you create the model.
    Click
    Next.
  7. Select the number of rows to import from the data source.
    By default, the Developer tool imports all rows from the data source. If you enter a number, the model counts the rows from the start of the data set.
  8. Click
    Finish
    , and save the model.
After you create the model, verify the label assignments and compile the model.
