  • Method Details

    • definitionName

      public final String definitionName()

      The job definition name.

      Returns:
      The job definition name.

    • tuningObjective

      public final HyperParameterTuningJobObjective tuningObjective()
      Returns the value of the TuningObjective property for this object.
      Returns:
      The value of the TuningObjective property for this object.

    • hyperParameterRanges

      public final ParameterRanges hyperParameterRanges()
      Returns the value of the HyperParameterRanges property for this object.
      Returns:
      The value of the HyperParameterRanges property for this object.

    • hasStaticHyperParameters

      public final boolean hasStaticHyperParameters()
      For responses, this returns true if the service returned a value for the StaticHyperParameters 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.

    • staticHyperParameters

      public final Map<String,String> staticHyperParameters()

      Specifies the values of hyperparameters that do not change for the tuning job.

      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 hasStaticHyperParameters() method.

      Returns:
      Specifies the values of hyperparameters that do not change for the tuning job.

    • algorithmSpecification

      public final HyperParameterAlgorithmSpecification algorithmSpecification()

      The HyperParameterAlgorithmSpecification object that specifies the resource algorithm to use for the training jobs that the tuning job launches.

      Returns:
      The HyperParameterAlgorithmSpecification object that specifies the resource algorithm to use for the training jobs that the tuning job launches.

    • roleArn

      public final String roleArn()

      The Amazon Resource Name (ARN) of the IAM role associated with the training jobs that the tuning job launches.

      Returns:
      The Amazon Resource Name (ARN) of the IAM role associated with the training jobs that the tuning job launches.

    • hasInputDataConfig

      public final boolean hasInputDataConfig()
      For responses, this returns true if the service returned a value for the InputDataConfig 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.

    • inputDataConfig

      public final List<Channel> inputDataConfig()

      An array of Channel objects that specify the input for the training jobs that the tuning job launches.

      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 hasInputDataConfig() method.

      Returns:
      An array of Channel objects that specify the input for the training jobs that the tuning job launches.

    • vpcConfig

      public final VpcConfig vpcConfig()

      The VpcConfig object that specifies the VPC that you want the training jobs that this hyperparameter tuning job launches to connect to. Control access to and from your training container by configuring the VPC. For more information, see Protect Training Jobs by Using an Amazon Virtual Private Cloud.

      Returns:

      public final OutputDataConfig outputDataConfig()

      Specifies the path to the Amazon S3 bucket where you store model artifacts from the training jobs that the tuning job launches.

      Returns:
      Specifies the path to the Amazon S3 bucket where you store model artifacts from the training jobs that the tuning job launches.

    • resourceConfig

      public final ResourceConfig resourceConfig()

      The resources, including the compute instances and storage volumes, to use for the training jobs that the tuning job launches.

      Storage volumes store model artifacts and incremental states. Training algorithms might also use storage volumes for scratch space. If you want SageMaker to use the storage volume to store the training data, choose File as the TrainingInputMode in the algorithm specification. For distributed training algorithms, specify an instance count greater than 1.

      If you want to use hyperparameter optimization with instance type flexibility, use HyperParameterTuningResourceConfig instead.

      Returns:
      The resources, including the compute instances and storage volumes, to use for the training jobs that the tuning job launches.

    • stoppingCondition

      public final StoppingCondition stoppingCondition()

      Specifies a limit to how long a model hyperparameter training job can run. It also specifies how long a managed spot training job has to complete. When the job reaches the time limit, SageMaker ends the training job. Use this API to cap model training costs.

      Returns:
      Specifies a limit to how long a model hyperparameter training job can run. It also specifies how long a managed spot training job has to complete. When the job reaches the time limit, SageMaker ends the training job. Use this API to cap model training costs.

    • enableNetworkIsolation

      public final Boolean enableNetworkIsolation()

      Isolates the training container. No inbound or outbound network calls can be made, except for calls between peers within a training cluster for distributed training. If network isolation is used for training jobs that are configured to use a VPC, SageMaker downloads and uploads customer data and model artifacts through the specified VPC, but the training container does not have network access.

      Returns:

      For responses, this returns true if the service returned a value for the Environment 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.

    • environment

      public final Map<String,String> environment()

      An environment variable that you can pass into the SageMaker CreateTrainingJob API. You can use an existing environment variable from the training container or use your own. See Define metrics and variables for more information.

      The maximum number of items specified for Map Entries refers to the maximum number of environment variables for each TrainingJobDefinition and also the maximum for the hyperparameter tuning job itself. That is, the sum of the number of environment variables for all the training job definitions can't exceed the maximum number specified.

      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 hasEnvironment() method.
