Enum RBFNet.Phase1Learner

java.lang.Object

java.lang.Enum<RBFNet.Phase1Learner>

jsat.classifiers.neuralnetwork.RBFNet.Phase1Learner

All Implemented Interfaces:

Serializable, Comparable<RBFNet.Phase1Learner>

Enclosing class:

RBFNet

public static enum RBFNet.Phase1Learner
extends Enum<RBFNet.Phase1Learner>

The first phase of learning a RBF Neural Network is to determine the neuron locations. This enum controls which method is used.

Enum Constant Detail

RANDOM

public static final RBFNet.Phase1Learner RANDOM

Selects the Neurons at random from the training data

K_MEANS

public static final RBFNet.Phase1Learner K_MEANS

Selects the Neurons by performing k-Means clustering on the data

Method Detail

values

public static RBFNet.Phase1Learner[] values()

Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:

for (RBFNet.Phase1Learner c : RBFNet.Phase1Learner.values())
    System.out.println(c);

Returns:

an array containing the constants of this enum type, in the order they are declared

valueOf

public static RBFNet.Phase1Learner valueOf(String name)

Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)

Parameters:

name - the name of the enum constant to be returned.

Returns:

the enum constant with the specified name

Throws:

IllegalArgumentException - if this enum type has no constant with the specified name

NullPointerException - if the argument is null

getCentroids

protected abstract List<Vec> getCentroids(DataSet data,
                                          int centroids,
                                          DistanceMetric dm,
                                          ExecutorService ex)

Obtains the centroids for the given data set

Parameters:

data - the data set to get the centroids for

centroids - the number of centroids to obtain

dm - the distance metric that is being used

ex - the source of threads for parallel computation

Returns:

a list of the centroid vectors
