Available on crate features job-service or vizier-service only.

Represents specification of a Study.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

metrics: Vec<MetricSpec>

Required. Metric specs for the Study.

parameters: Vec<ParameterSpec>

Required. The set of parameters to tune.

algorithm: Algorithm

The search algorithm specified for the Study.

observation_noise: ObservationNoise

The observation noise level of the study. Currently only supported by the Vertex AI Vizier service. Not supported by HyperparameterTuningJob or TrainingPipeline.

measurement_selection_type: MeasurementSelectionType

Describe which measurement selection type will be used

study_stopping_config: Option<StudyStoppingConfig>

Conditions for automated stopping of a Study. Enable automated stopping by configuring at least one condition.

automated_stopping_spec: Option<AutomatedStoppingSpec>
