All Implemented Interfaces:

Engine

public class JLibSVMBinaryEngine
extends java.lang.Object
implements Engine

The Class JLibSVMBinaryEngine 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 one VS all binary classifiers, which means that several labels can be assigned to a given object
