Enum Constant Details

EXPECTED_IMPROVEMENT

public static final BayesianOptimization.Acquisition EXPECTED_IMPROVEMENT

Expected Improvement (EI). Measures the expected amount by which a candidate configuration improves upon the current best observed value.

UPPER_CONFIDENCE_BOUND

public static final BayesianOptimization.Acquisition UPPER_CONFIDENCE_BOUND

Upper Confidence Bound (UCB). Selects candidates based on an optimistic confidence bound mu + kappa * sigma.

PROBABILITY_OF_IMPROVEMENT

public static final BayesianOptimization.Acquisition PROBABILITY_OF_IMPROVEMENT

Probability of Improvement (PI). Computes the probability that a candidate configuration will improve upon the current best observed value.

Method Details

values

public static BayesianOptimization.Acquisition[] values()

Returns an array containing the constants of this enum class, in the order they are declared.

Returns:

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

valueOf

public static BayesianOptimization.Acquisition valueOf(String name)

Returns the enum constant of this class with the specified name. The string must match exactly an identifier used to declare an enum constant in this class. (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 class has no constant with the specified name

NullPointerException - if the argument is null
