All Implemented Interfaces:

Engine

public class JLibSVMMulticlassEngine
extends java.lang.Object
implements Engine

The Class JLibSVMMulticlassEngine is an implementation of an Engine that produces models by using the SVM engine from JLibSVM.

It receives as input a structure configuration and a set of relationship extractions to be extracted.

The model produced by this engine will use multi-label classifiers, which means that only one label can be assigned to a given object.
