Method Detail

getNumOfInputs

public int getNumOfInputs()

Specified by:

getNumOfInputs in interface Experiment

getNumOfOutputs

public int getNumOfOutputs()

Specified by:

getNumOfOutputs in interface Experiment

generateInput

public SampleData[] generateInput()

Generate input using default parameters

Specified by:

generateInput in interface Experiment

generateInput

public SampleData[] generateInput(int inputSampleSeparation)

generates an array of inputs suitable for this experiment.

Specified by:

generateInput in interface Experiment

Parameters:

inputSampleSeparation - relative frequency of input to output samples. If this is n, then n outputs will be sampled for every change in inputs.

generateInput

public SampleData[] generateInput(int inputSampleSeparation,
                                  int inputDataLength)

Generate input suitable for testing this experiment using custom parameters

Parameters:

inputDataLength - how long the input data should be

inputSampleSeparation - how often the input samples should change in time. Greater value -> less often

getFitness

public double getFitness(SampleData[] in,
                         SampleData[] out)

Description copied from interface: Experiment

returns a fitness associated to a given input/output pair for this experiment. The fitness is a double and is in adjusted fitness format. From 0 to 1, 1 being perfectly fit.

Specified by:

getFitness in interface Experiment

Following copied from interface: jaga.experiment.Experiment

Parameters:

in - array of inputs

out - array of outputs

toString

public java.lang.String toString()

Overrides:

toString in class java.lang.Object

set

public void set(java.lang.Object param)

Sets random seed for inputs generation to param where param instanceof Long

Specified by:

set in interface ConfigurableExperiment

get

public java.lang.Object get(java.lang.Object param)

Specified by:

get in interface ConfigurableExperiment
