Field Detail

MINIMA_ID

public static final OptionID MINIMA_ID

Parameter for minimum.

MAXIMA_ID

public static final OptionID MAXIMA_ID

Parameter for maximum.

maxima

private double[] maxima

Stores the maximum in each dimension.

minima

private double[] minima

Stores the minimum in each dimension.

SEED_ID

public static final OptionID SEED_ID

Optional parameter to specify a seed for random Gaussian noise generation. If unused, system time is used as seed.

seed

protected java.lang.Long seed

Seed for randomly shuffling the rows of the database. If null, system time is used as seed.

PERCENTAGE_ID

public static final OptionID PERCENTAGE_ID

Optional parameter to specify a percentage of the standard deviation of the random Gaussian noise generation, given the standard deviation of the corresponding attribute in the original data distribution (assuming a Gaussian there).

SCALINGREFERENCE_ID

public static final OptionID SCALINGREFERENCE_ID

Parameter for selecting scaling reference.

NOISEDISTRIBUTION_ID

public static final OptionID NOISEDISTRIBUTION_ID

Parameter for selecting the noise distribution.

percentage

protected double percentage

Percentage of the variance of the random Gaussian noise generation or of the range of the uniform distribution, given the variance of the corresponding attribute in the data.

scalingreference

protected PerturbationFilter.ScalingReference scalingreference

The option which reference to use for scaling the noise.

noisedistribution

protected PerturbationFilter.NoiseDistribution noisedistribution

The option which nature of noise distribution to choose.

Method Detail

configure

public void configure(Parameterization config)

Description copied from interface: Parameterizer

Configure the class.

Note: the status is collected by the parameterization object, so that multiple errors may arise and be reported in one run.

Specified by:

configure in interface Parameterizer

Parameters:

config - Parameterization

make

public PerturbationFilter<V> make()

Description copied from interface: Parameterizer

Make an instance after successful configuration.

Note: your class should return the exact type, only this very broad interface should use Object as return type.

Specified by:

make in interface Parameterizer

Returns:

a new instance
