Enum Operation

java.lang.Object

java.lang.Enum<Operation>

org.nd4j.autodiff.listeners.Operation

All Implemented Interfaces:

Serializable, Comparable<Operation>

public enum Operation
extends Enum<Operation>

An enum representing the operation being done on a SameDiff graph.

TRAINING: SameDiff.fit() methods training step (everything except validation)
TRAINING_VALIDATION: the validation step during SameDiff.fit() methods - i.e., test/validation set evaluation,
INFERENCE: SameDiff.output(), SameDiff.batchOutput() and SameDiff#exec(Map, String...) ()} methods, including the single batch and placeholder ones. Also SDVariable.eval()
EVALUATION: SameDiff.evaluate() methods

Enum Constant Summary

EVALUATION Evaluation operations: SameDiff.evaluate() methods.
INFERENCE Inference operations: SameDiff.output(), SameDiff.batchOutput() and SameDiff#exec(Map, String...) ()} methods, as well as SameDiff#execBackwards(Map, Operation, String...) methods.
TRAINING The training operation: SameDiff.fit() methods training step (everything except validation).
TRAINING_VALIDATION The training validation operation: the validation step during SameDiff.fit() methods.

Enum Constant Detail

TRAINING

public static final Operation TRAINING

The training operation: SameDiff.fit() methods training step (everything except validation).

TRAINING_VALIDATION

public static final Operation TRAINING_VALIDATION

The training validation operation: the validation step during SameDiff.fit() methods.

INFERENCE

public static final Operation INFERENCE

Inference operations: SameDiff.output(), SameDiff.batchOutput() and SameDiff#exec(Map, String...) ()} methods, as well as SameDiff#execBackwards(Map, Operation, String...) methods.

EVALUATION

public static final Operation EVALUATION

Evaluation operations: SameDiff.evaluate() methods.

Method Detail

values

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

Returns:

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

valueOf

public static Operation 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

isTrainingPhase

public boolean isTrainingPhase()

isValidation

public boolean isValidation()
