- To change the label of an image that you added to a class, use the action `RelabelClassImage`.
- To move an image from one class to another, for example if you add an image to the wrong class, use the action `MoveClassImage`.
- To add, remove, or update custom metadata for a class, use the actions `AddClassMetadata`, `RemoveClassMetadata`, and `UpdateClassMetadata`.
- To rename a class, use the action `RenameClass`.
- To remove a class from a classifier and discard all associated images and metadata, use the action `RemoveClass`.

- To modify the training options for a classifier, use the actions `SetClassifierTrainingOption` and `UnsetClassifierTrainingOption`.
- To rename a classifier, use the action `RenameClassifier`.
