All Implemented Interfaces:

Uncertainifier<UnweightedDiscreteUncertainObject>

public class UnweightedDiscreteUncertainifier
extends AbstractDiscreteUncertainifier<UnweightedDiscreteUncertainObject>

Class to generate unweighted discrete uncertain objects.

This is a second-order generator: it requires the use of another generator to sample from (e.g., UniformUncertainifier or SimpleGaussianUncertainifier).

Since:

0.7.0

UnweightedDiscreteUncertainifier

public UnweightedDiscreteUncertainifier(Uncertainifier<?> inner,
                                        int minQuant,
                                        int maxQuant)

Constructor.

inner - Inner uncertainifier

minQuant - Minimum number of samples

maxQuant - Maximum number of samples

Method Detail

newFeatureVector

public <A> UnweightedDiscreteUncertainObject 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);
 

Type Parameters:

A - Array type

Parameters:

rand - Random generator

array - Array

adapter - Array type adapter

Returns:

Uncertain object

getFactory

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

Description copied from interface: Uncertainifier

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

Returns:

Vector factory.
