Enum Constant Details

CROSS_ENTROPY

public static final ArtificialNeuralNetwork.Error CROSS_ENTROPY

Currently this can only be used in combination with ArtificialNeuralNetwork.Activator.SOFTMAX in the final layer. All other usage will give incorrect network training.

HALF_SQUARED_DIFFERENCE

public static final ArtificialNeuralNetwork.Error HALF_SQUARED_DIFFERENCE

Method Details

values

public static ArtificialNeuralNetwork.Error[] 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 ArtificialNeuralNetwork.Error 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
