Constructor Detail

SimpleGaussianUncertainifier

public SimpleGaussianUncertainifier(double minDev,
                                    double maxDev,
                                    boolean symmetric)

Constructor.

Parameters:

minDev - Minimum deviation

maxDev - Maximum deviation

symmetric - Generate symmetric distributions only

Method Detail

newFeatureVector

public <A> SimpleGaussianContinuousUncertainObject newFeatureVector(java.util.Random rand,
                                                                    A array,
                                                                    NumberArrayAdapter<?,A> adapter)

Description copied from interface: Uncertainifier

Generate a new uncertain object. This interface is specialized to numerical arrays. The generics allow the use with primitive double[] arrays:

 UO obj = newFeatureVector(array, ArrayLikeUtil.DOUBLEARRAYADAPTER);
 

Specified by:

newFeatureVector in interface Uncertainifier<SimpleGaussianContinuousUncertainObject>

Type Parameters:

A - Array type

Parameters:

rand - Random generator

array - Array

adapter - Array type adapter

Returns:

Uncertain object

getFactory

public FeatureVector.Factory<SimpleGaussianContinuousUncertainObject,?> getFactory()

Description copied from interface: Uncertainifier

Get the vector factory used for type information and serialization (if supported).

Specified by:

getFactory in interface Uncertainifier<SimpleGaussianContinuousUncertainObject>

Returns:

Vector factory.
