  - buildClassifier
```
void buildClassifier(Database database,
                     Relation<? extends ClassLabel> classLabels)
```
    Performs the training. Sets available labels.
    
    Parameters:
    
    database - the database to build the model on
    
    classLabels - the classes to be learned
  - classify
```
ClassLabel classify(O instance)
```
    Classify a single instance.
    
    Parameters:
    
    instance - an instance to classify
    
    Returns:
    
    predicted class label of the given instance
  - model
```
java.lang.String model()
```
    Produce a String representation of the classification model.
    
    Returns:
    
    a String representation of the classification model
