MultiTrialAlgorithmSpec(mapping=None, *, ignore_unknown_fields=False, **kwargs)

The spec of multi-trial Neural Architecture Search (NAS).

Attributes
Name	Description
multi_trial_algorithm	google.cloud.aiplatform_v1beta1.types.NasJobSpec.MultiTrialAlgorithmSpec.MultiTrialAlgorithm The multi-trial Neural Architecture Search (NAS) algorithm type. Defaults to REINFORCEMENT_LEARNING.
metric	google.cloud.aiplatform_v1beta1.types.NasJobSpec.MultiTrialAlgorithmSpec.MetricSpec Metric specs for the NAS job. Validation for this field is done at multi_trial_algorithm_spec field.
search_trial_spec	google.cloud.aiplatform_v1beta1.types.NasJobSpec.MultiTrialAlgorithmSpec.SearchTrialSpec Required. Spec for search trials.
train_trial_spec	google.cloud.aiplatform_v1beta1.types.NasJobSpec.MultiTrialAlgorithmSpec.TrainTrialSpec Spec for train trials. Top N [TrainTrialSpec.max_parallel_trial_count] search trials will be trained for every M [TrainTrialSpec.frequency] trials searched.
