public class PSOSVM
extends AbstractLearner

This is a SVM implementation using a particle swarm optimization (PSO) approach to solve the dual optimization problem of a SVM. It turns out that on many datasets this simple implementation is as fast and accurate as the usual SVM implementations.

PSOSVM

public PSOSVM(OperatorDescription description)

Creates a new SVM which uses a particle swarm optimization approach for optimization.

Method Detail

learn

public Model learn(ExampleSet exampleSet)
            throws OperatorException

Learns and returns a model.

Throws:

OperatorException

supportsCapability

public boolean supportsCapability(LearnerCapability lc)

Returns true for numerical attributes, binominal classes, and numerical target attributes.

getParameterTypes

public java.util.List<ParameterType> getParameterTypes()

Description copied from class: Operator

Returns a list of ParameterTypes describing the parameters of this operator. The default implementation returns an empty list if no input objects can be retained and special parameters for those input objects which can be prevented from being consumed.

Overrides:
