evaluations

public ListenerEvaluations evaluations()

Description copied from class: BaseEvaluationListener

Return the requested evaluations. New instances of these evaluations will be made each time they are used

Specified by:

evaluations in class BaseEvaluationListener

isActive

public boolean isActive(Operation operation)

Description copied from interface: Listener

Returns whether this listener is active during the given operation. If this returns false for the given operation, those listener methods will not be called.

epochEndEvaluations

public ListenerResponse epochEndEvaluations(SameDiff sd,
                                            At at,
                                            LossCurve lossCurve,
                                            long epochTimeMillis,
                                            EvaluationRecord evaluations)

Description copied from class: BaseEvaluationListener

See Listener.epochEnd(SameDiff, At, LossCurve, long), also provided the requested evaluations

Overrides:

epochEndEvaluations in class BaseEvaluationListener

validationDoneEvaluations

public ListenerResponse validationDoneEvaluations(SameDiff sd,
                                                  At at,
                                                  long validationTimeMillis,
                                                  EvaluationRecord evaluations)

Description copied from class: BaseEvaluationListener

See Listener.validationDone(SameDiff, At, long), also provided the requested evaluations

Overrides:

validationDoneEvaluations in class BaseEvaluationListener

operationStart

public void operationStart(SameDiff sd,
                           Operation op)

Description copied from interface: Listener

Called at the start of an operation, e.g. training or validation

Specified by:

operationStart in interface Listener

Overrides:

operationStart in class BaseListener

Parameters:

sd - The SameDiff instance

op - The operation being started

operationEnd

public void operationEnd(SameDiff sd,
                         Operation op)

Description copied from interface: Listener

Called at the end of an operation, e.g. training or validation

Specified by:

operationEnd in interface Listener

Overrides:

operationEnd in class BaseListener

Parameters:

sd - The SameDiff instance

op - The operation being started

getReport

public History getReport()
