Reference documentation and code samples for the Vertex AI V1 API module Google::Cloud::AIPlatform::V1::StudySpec::ObservationNoise.

Describes the noise level of the repeated observations.

"Noisy" means that the repeated observations with the same Trial parameters may lead to different metric evaluations.

Constants

OBSERVATION_NOISE_UNSPECIFIED

value: 0
The default noise level chosen by Vertex AI.

LOW

value: 1
Vertex AI assumes that the objective function is (nearly) perfectly reproducible, and will never repeat the same Trial parameters.

HIGH

value: 2
Vertex AI will estimate the amount of noise in metric evaluations, it may repeat the same Trial parameters more than once.
