  2. (Optional) Select one or more models to be retrained. To select all models, select the Select All check box.
  3. Select a destination version for new models.
    Note: If you do not select a destination version, the default location is used for the destination of the new retrained models.
    (Optional) To create a new version to store the new retrained models:
    1. From the Select Models for Retrain page of the wizard, click New. The New Version window appears.

You can either use the whole training data source to compare or partition it into two parts, based on partition percent and random seed. The percent that is specified is the percentage of data that is used for model comparison; the other part of the data is used for training. The random seed value is used to generate the training data based on the random sampling method.
    • Click the Browse to select a performance data set as the comparison data source.
  14. Specify the report options.
