All Implemented Interfaces:

Serializable, Comparable<SamplingScoreBasedClassifier.SamplingScheme>

Enclosing class:

SamplingScoreBasedClassifier

public static enum SamplingScoreBasedClassifier.SamplingScheme
extends Enum<SamplingScoreBasedClassifier.SamplingScheme>

Sampling scheme for sampling the parameters of the scoring functions. While sampling all parameters in each step may lead to low acceptance rates, it may be suited for scoring functions with low number of parameters, or in cases where an intuitive grouping of parameters is not possible. On the other hand, grouped sampling may escape local maxima only after a large number of sampling steps. Sampling function-wise sampled parameters grouped by scoring functions.

Enum Constant Detail

ALL_PARAMETERS

public static final SamplingScoreBasedClassifier.SamplingScheme ALL_PARAMETERS

All parameters are drawn before decision of acceptance

FUNCTION_WISE

public static final SamplingScoreBasedClassifier.SamplingScheme FUNCTION_WISE

The parameters of each function are drawn before decision of acceptance

GROUPED

public static final SamplingScoreBasedClassifier.SamplingScheme GROUPED

The parameters of each group are drawn before decision of acceptance

Method Detail

values

public static SamplingScoreBasedClassifier.SamplingScheme[] 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 (SamplingScoreBasedClassifier.SamplingScheme c : SamplingScoreBasedClassifier.SamplingScheme.values())
    System.out.println(c);

Returns:

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

valueOf

public static SamplingScoreBasedClassifier.SamplingScheme 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
