Choose the corresponding class
Choose the Corresponding class from the drop-down list. That class will be returned when the particular rule is applied.
Set class parameters for rule application
For every class, you can set parameters that will cause a rule to be applied. To do this, select Properties in the class shortcut menu in the Classifier window.- If the class can be confused with others during classification, select the Add classes to this classification result check box, and then click Edit and specify the particular classes that can be confused.
- If you are planning to use rules to improve the quality of auto-classification, select the Improve auto-classification result using rule tree check box. Next, specify which rules are going to be used if this particular class is assigned as a result of auto-classification:
- Use rules for corresponding classes only – Only the rules specified for the “confusing” classes in the list will be applied.
- Use all rules – All existing rules will be used until one is successfully applied. If none of the rules are successfully applied, the auto-classification result will not change.
