Generating a Filter from a Feature Selection Model

Based on the results of a Feature Selection model, you can use the Generate Filter from Feature dialog box to generate one or more Filter nodes that include or exclude subsets of fields based on importance relative to the specified target. While the model nugget can also be used as a filter, this gives you the flexibility to experiment with different subsets of fields without copying or modifying the model. The target field is always preserved by the filter regardless of whether include or exclude is selected.

Include/Exclude. You can choose to include or exclude fields—for example, to include the top 10 fields or exclude all fields marked as unimportant.

Selected fields. Includes or excludes all fields currently selected in the table.

All fields marked. Selects all fields marked as important, marginal, or unimportant.

Top number of fields. Allows you to select the top n fields based on importance.

Importance greater than. Selects all fields with importance greater than the specified threshold.
