Enum Constant Detail

MEAN_SQUARED_ERROR

public static final Cost MEAN_SQUARED_ERROR

Mean squares error cost.

LIKELIHOOD

public static final Cost LIKELIHOOD

Negative likelihood (or log-likelihood) cost. It is equivalently described as the cross-entropy in classification.

Method Detail

values

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

Returns:

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

valueOf

public static Cost valueOf(java.lang.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:

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

java.lang.NullPointerException - if the argument is null
