Instance Attribute Details
#algorithm ⇒ String
Optional. The search algorithm specified for the hyperparameter
tuning job.
Uses the default CloudML Engine hyperparameter tuning
algorithm if unspecified.
Corresponds to the JSON property algorithm

# File 'generated/google/apis/ml_v1/classes.rb', line 305 def algorithm @algorithm end |
#enable_trial_early_stopping ⇒ Boolean Also known as: enable_trial_early_stopping?
Optional. Indicates if the hyperparameter tuning job enables auto trial
early stopping.
Corresponds to the JSON property enableTrialEarlyStopping

#goal ⇒ String
Required. The type of goal to use for tuning. Available types are
MAXIMIZE
and MINIMIZE
.
Defaults to MAXIMIZE
.
Corresponds to the JSON property goal

# File 'generated/google/apis/ml_v1/classes.rb', line 319 def goal @goal end |
#hyperparameter_metric_tag ⇒ String
Optional. The Tensorflow summary tag name to use for optimizing trials. For
current versions of Tensorflow, this tag name should exactly match what is
shown in Tensorboard, including all scopes. For versions of Tensorflow
prior to 0.12, this should be only the tag passed to tf.Summary.
By default, "training/hptuning/metric" will be used.
Corresponds to the JSON property hyperparameterMetricTag

#max_parallel_trials ⇒ Fixnum
Optional. The number of training trials to run concurrently.
You can reduce the time it takes to perform hyperparameter tuning by adding
trials in parallel. However, each trail only benefits from the information
gained in completed trials. That means that a trial does not get access to
the results of trials running at the same time, which could reduce the
quality of the overall optimization.
Each trial will use the same scale tier and machine types.
Defaults to one.
Corresponds to the JSON property maxParallelTrials
340 341 342 |
# File 'generated/google/apis/ml_v1/classes.rb', line 340 def max_parallel_trials @max_parallel_trials end |
#max_trials ⇒ Fixnum
Optional. How many training trials should be attempted to optimize
the specified hyperparameters.
Defaults to one.
Corresponds to the JSON property maxTrials
347 348 349 |
# File 'generated/google/apis/ml_v1/classes.rb', line 347 def max_trials @max_trials end |
#params ⇒ Array<Google::Apis::MlV1::GoogleCloudMlV1ParameterSpec>
Required. The set of parameters to tune.
Corresponds to the JSON property params

# File 'generated/google/apis/ml_v1/classes.rb', line 352 def params @params end |
#resume_previous_job_id ⇒ String
Optional. The prior hyperparameter tuning job id that users hope to
continue with. The job id will be used to find the corresponding vizier
study guid and resume the study.
Corresponds to the JSON property resumePreviousJobId
