Enum Regularization.ApplyStep

java.lang.Object

java.lang.Enum<Regularization.ApplyStep>

org.nd4j.linalg.learning.regularization.Regularization.ApplyStep

All Implemented Interfaces:

Serializable, Comparable<Regularization.ApplyStep>

Enclosing interface:

Regularization

public static enum Regularization.ApplyStep
extends Enum<Regularization.ApplyStep>

ApplyStep determines how the regularization interacts with the optimization process - i.e., when it is applied relative to updaters like Adam, Nesterov momentum, SGD, etc.

BEFORE_UPDATER: w -= updater(gradient + regularization(p,gradView,lr))
POST_UPDATER: w -= (updater(gradient) + regularization(p,gradView,lr))

Method Detail

values

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

Returns:

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

valueOf

public static Regularization.ApplyStep 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
