Constants

$default → const StudySpec_ObservationNoise
The default value for StudySpec_ObservationNoise.
high → const StudySpec_ObservationNoise
Vertex AI will estimate the amount of noise in metric evaluations, it may repeat the same Trial parameters more than once.
low → const StudySpec_ObservationNoise
Vertex AI assumes that the objective function is (nearly) perfectly reproducible, and will never repeat the same Trial parameters.
observationNoiseUnspecified → const StudySpec_ObservationNoise
The default noise level chosen by Vertex AI.
