Class HyperParameterTrainingJobSummary

    • Method Detail

      • trainingJobDefinitionName

        public final String trainingJobDefinitionName()

        The training job definition name.

        Returns:
        The training job definition name.
      • trainingJobName

        public final String trainingJobName()

        The name of the training job.

        Returns:
        The name of the training job.
      • trainingJobArn

        public final String trainingJobArn()

        The Amazon Resource Name (ARN) of the training job.

        Returns:
        The Amazon Resource Name (ARN) of the training job.
      • tuningJobName

        public final String tuningJobName()

        The HyperParameter tuning job that launched the training job.

        Returns:
        The HyperParameter tuning job that launched the training job.
      • creationTime

        public final Instant creationTime()

        The date and time that the training job was created.

        Returns:
        The date and time that the training job was created.
      • trainingStartTime

        public final Instant trainingStartTime()

        The date and time that the training job started.

        Returns:
        The date and time that the training job started.
      • trainingEndTime

        public final Instant trainingEndTime()

        Specifies the time when the training job ends on training instances. You are billed for the time interval between the value of TrainingStartTime and this time. For successful jobs and stopped jobs, this is the time after model artifacts are uploaded. For failed jobs, this is the time when SageMaker detects a job failure.

        Returns:
        Specifies the time when the training job ends on training instances. You are billed for the time interval between the value of TrainingStartTime and this time. For successful jobs and stopped jobs, this is the time after model artifacts are uploaded. For failed jobs, this is the time when SageMaker detects a job failure.
      • hasTunedHyperParameters

        public final boolean hasTunedHyperParameters()
        For responses, this returns true if the service returned a value for the TunedHyperParameters property. This DOES NOT check that the value is non-empty (for which, you should check the isEmpty() method on the property). This is useful because the SDK will never return a null collection or map, but you may need to differentiate between the service returning nothing (or null) and the service returning an empty collection or map. For requests, this returns true if a value for the property was specified in the request builder, and false if a value was not specified.
      • tunedHyperParameters

        public final Map<String,​String> tunedHyperParameters()

        A list of the hyperparameters for which you specified ranges to search.

        Attempts to modify the collection returned by this method will result in an UnsupportedOperationException.

        This method will never return null. If you would like to know whether the service returned this field (so that you can differentiate between null and empty), you can use the hasTunedHyperParameters() method.

        Returns:
        A list of the hyperparameters for which you specified ranges to search.
      • failureReason

        public final String failureReason()

        The reason that the training job failed.

        Returns:
        The reason that the training job failed.
      • objectiveStatus

        public final ObjectiveStatus objectiveStatus()

        The status of the objective metric for the training job:

        • Succeeded: The final objective metric for the training job was evaluated by the hyperparameter tuning job and used in the hyperparameter tuning process.

        • Pending: The training job is in progress and evaluation of its final objective metric is pending.

        • Failed: The final objective metric for the training job was not evaluated, and was not used in the hyperparameter tuning process. This typically occurs when the training job failed or did not emit an objective metric.

        If the service returns an enum value that is not available in the current SDK version, objectiveStatus will return ObjectiveStatus.UNKNOWN_TO_SDK_VERSION. The raw value returned by the service is available from objectiveStatusAsString().

        Returns:
        The status of the objective metric for the training job:

        • Succeeded: The final objective metric for the training job was evaluated by the hyperparameter tuning job and used in the hyperparameter tuning process.

        • Pending: The training job is in progress and evaluation of its final objective metric is pending.

        • Failed: The final objective metric for the training job was not evaluated, and was not used in the hyperparameter tuning process. This typically occurs when the training job failed or did not emit an objective metric.
