Instance Attribute Details
#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

#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

#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

Required. The set of parameters to tune.
Corresponds to the JSON property params
