Uses of Operation in org.nd4j.autodiff.listeners

Methods in org.nd4j.autodiff.listeners that return Operation

Modifier and Type	Method and Description
Operation	At.operation()
static Operation	Operation.valueOf(String name) Returns the enum constant of this type with the specified name.
static Operation[]	Operation.values() Returns an array containing the constants of this enum type, in the order they are declared.

Methods in org.nd4j.autodiff.listeners with parameters of type Operation

Modifier and Type	Method and Description
At	At.copy(Operation operation)
static At	At.defaultAt(Operation op)
boolean	Listener.isActive(Operation operation) Returns whether this listener is active during the given operation.
void	Listener.operationEnd(SameDiff sd, Operation op) Called at the end of an operation, e.g.
void	BaseListener.operationEnd(SameDiff sd, Operation op)
void	Listener.operationStart(SameDiff sd, Operation op) Called at the start of an operation, e.g.
void	BaseListener.operationStart(SameDiff sd, Operation op)
Set<String>	ListenerVariables.requiredVariables(Operation op) Get required variables for specified op
ListenerVariables.Builder	ListenerVariables.Builder.requireVariables(Operation op, SDVariable... variables) Add required variables for the specified op
ListenerVariables.Builder	ListenerVariables.Builder.requireVariables(Operation op, String... variables) Add required variables for the specified op

Uses of Operation in org.nd4j.autodiff.listeners.checkpoint

Methods in org.nd4j.autodiff.listeners.checkpoint with parameters of type Operation

Modifier and Type	Method and Description
boolean	CheckpointListener.isActive(Operation operation)

Uses of Operation in org.nd4j.autodiff.listeners.debugging

Methods in org.nd4j.autodiff.listeners.debugging with parameters of type Operation

Modifier and Type	Method and Description
boolean	ExecDebuggingListener.isActive(Operation operation)

Uses of Operation in org.nd4j.autodiff.listeners.impl

Methods in org.nd4j.autodiff.listeners.impl with parameters of type Operation

Modifier and Type	Method and Description
boolean	UIListener.isActive(Operation operation)
boolean	ScoreListener.isActive(Operation operation)
boolean	HistoryListener.isActive(Operation operation)
void	HistoryListener.operationEnd(SameDiff sd, Operation op)
void	HistoryListener.operationStart(SameDiff sd, Operation op)

Uses of Operation in org.nd4j.autodiff.samediff

Methods in org.nd4j.autodiff.samediff with parameters of type Operation

Modifier and Type	Method and Description
Map<String,INDArray>	SameDiff.execBackwards(Map<String,INDArray> placeholders, List<String> variableGradNamesList, Operation operation) As per SameDiff.execBackwards(Map, Operation, MultiDataSet, Collection, List), but the set of gradients to calculate can be specified manually. For example, to calculate the gradient for placeholder variable "myPlaceholder", use execBackwards(placeholders, Arrays.asList(myPlaceholder.gradient().getVarName()).
protected Map<String,INDArray>	SameDiff.execBackwards(Map<String,INDArray> placeholders, List<String> variableGradNamesList, Operation operation, MultiDataSet batch, Collection<String> requiredActivations, List<Listener> activeListeners)
void	SameDiff.execBackwards(Map<String,INDArray> placeholders, Operation op) Create (if required) and then calculate the variable gradients (backward pass) for this graph. After execution, the gradient arrays can be accessed using myVariable.getGradient().getArr() Note: This method by default calculates VARIABLE type SDVariable gradients only (as well as any other gradients needed to calculate the variable gradients).
protected void	SameDiff.execBackwards(Map<String,INDArray> placeholders, Operation op, MultiDataSet batch, Collection<String> requiredActivations, List<Listener> activeListeners)
Map<String,INDArray>	SameDiff.execBackwards(Map<String,INDArray> placeholders, Operation op, String... variableGradNamesList) See SameDiff.execBackwards(Map, List, Operation)
