Class StochasticTrainingSetScore

java.lang.Object

org.encog.neural.networks.training.StochasticTrainingSetScore

All Implemented Interfaces:

CalculateScore

public class StochasticTrainingSetScore
extends java.lang.Object
implements CalculateScore

Calculate a score based on a training set. This class allows simulated annealing or genetic algorithms just as you would any other training set based training method. The method must support regression (MLRegression). A random sample is used to score the model.

Constructor Detail

StochasticTrainingSetScore

public StochasticTrainingSetScore(MLDataSet training,
                                  int theSize)

Construct a training set score calculation.

Parameters:

training - The training data to use.

Method Detail

calculateScore

public double calculateScore(MLMethod method)

Calculate the score for the network.

Specified by:

calculateScore in interface CalculateScore

Parameters:

method - The network to calculate for.

Returns:

The score.

shouldMinimize

public boolean shouldMinimize()

A training set based score should always seek to lower the error, as a result, this method always returns true.

Specified by:

shouldMinimize in interface CalculateScore

Returns:

Returns true.

requireSingleThreaded

public boolean requireSingleThreaded()

Specified by:

requireSingleThreaded in interface CalculateScore

Returns:

True, if this score function cannot be done in parallel.
