# ClassifierDeleteClass

Delete a class from a specified classifier.

You must set ClassifierName to the name of the classifier, and set ClassName to the name of the class that you want to delete. The action deletes the class and its training information (but it does not delete the training documents from the index).

After you delete a class, IDOL Server automatically retrains the classifier.
