To begin, you must choose features that you think will inform the predictions. Distil will use the chosen features to automatically generate models that predict the target.

Select the features to model

To choose the features that your model should use in its predictions:
  1. Click Add under the Horsepower and Cylinders features to send them to the list of Features to Model.

    Add cylinders to features to model
    Click Remove under the feature name in the Features to Model pane or click Remove All above the list of features.
    Remove feature from the features to model
  2. Note the distribution of categories for the Cylinders feature. Four, six and eight cylinder engines appear often, while three and five cylinder engines appear much less frequently.

    Distribution of cylinder values in the dataset
  3. Click the three-cylinder category to view samples that match the value in the Samples to Model From table.
  4. To exclude these samples from the model, click Exclude.
    Omit records with a specific categorical value
  5. Repeat steps 3–4 for the five-cylinder category as well.
  6. Review the updated Samples to Model From table. Click the column headers to sort by feature and check for extreme values that may indicate problems with the data. Note that several rows have no value for Horsepower.

    Record with no horsepower value
  7. To remove these records, click each row and then click Exclude.

    Omit records with no horsepower value
  8. Click Excluded Samples to review the records you removed. There is a collection of three and five cylinder vehicles, as well as some four cylinder vehicles with no horsepower.

Generate the models

You can now begin the model generation. Based on your selections, Distil:

  1. Automatically determines the number and type of models to predict your target feature.
  2. Uses a subset of the actual data to train the models to predict the target using the features selected in this step.
  3. Applies the trained models to the rest of the actual data to predict the target feature value in each record.
To begin the model generation with the current feature selections:
  • Click Create Models.
Create models

In this example, Distil will attempt to predict Acceleration based on the Horsepower and Cylinders features for a subset of the dataset.

Next steps

Review the generated models to determine whether they accurately predict the target feature.
